Like Idi0tequ3 said.

Apparently 7% of caucasians have an enzyme deficiency. CYP2D6 if im not mistaken.
I put it in inverted commas because im not a fan of statistics. Theyr 90% bullshit. haha

If your unlucky to have this deficiency you risk getting the itchies and other side effects. Codeine might give you this as its metabolized by the same enzyme but not to as such a high degree as DXM.

I very much agree with this. Personally I dont think its worth doing a drug unless you do it properly (except maybe weed). I usually take around 10mg/kg to 14mg/kg. Since I like DXM very much for a boring night with nothing to do.
I wont believe anyone who says they get dissociative effects with less than 300mg

DXM trips vary depending on dosage, and can be lumped into four very different plateaus, or types of trips, depending on the amount taken. Dosages are given in milligrams per kilogram, so multiply the figure by your mass in kg (or pounds divided by 2.2).

The first plateau, 1.5 to 2.5 mg/kg, is like a slightly intoxicating stimulant; music and movement are often pleasurable.
The second plateau, 2.5 to 7.5 mg/kg, is intoxicating, with a "stoning" a bit like that of nitrous oxide or marijuana; sounds and sights seem to be on strobe-effect ("flanging"), short-term memory is somewhat disrupted, and there are occasional mild hallucinations.
The third plateau, at 7.5 to 15mg/kg, consists of strong intoxication, hallucinations, and overall disturbances in thinking, senses, and memory; third plateau trips can be unpleasant.
The fourth plateau, above 15mg/kg, is similar to a sub-anesthetic dose of ketamine, with dissociation of the mind from the body, and may be dangerous physically and psychologically.

Most recreational use of DXM happens at the first and second plateau. DXM starts to become toxic around 20 to 30mg/kg.

Always test for unusual enzyme activity first by taking 100mg (105mg) in this case and sitting it out. It can be worse than just itchyness. There are two types of "deficiency".

If you don't notice any side effects (you shouldn't at this dose), then next time increase the dose to the desired plateau.

i took 20 tablets but fell asleep before they kicked in, but it woke me up when they did, thats for sure. i got really weird body high, like being an astronaunt, and crazy closed eye visuals. i couldnt focus on shit, i couldnt read. i coild barley figure out which CD to put on from my CD rack. i gotta do more to get a better effect. Overall i liked it

Yea you really do need more than that to get the 'proper' trip. But its good that you tried a lowish dose first to test the waters. If you didnt get any itchiness or other side effects, bump up the dose next time to maybe 450-500mg


Stay away from those datura plants

This is actually a very well supported statistic. There is even a gene chip on the market now that will measure your CYP2D6 enzyme levels because it is so critical in determining dosages for many drugs. Here's a tidbit I found:


The spectrum of activities results from allelic variants of CYP2D6 and can lead to unwanted consequences upon assuming a standard dosing regimen based upon an average CYP2D6 activity. In fact, given this distribution of activities, upwards of 15% of patients will be left either essentially untreated or reacting to diverse drug complications without monitoring.

CYP2D6 metabolizes 25-30% of all clinically used drugs, including beta-blockers (e.g., metoprolol, carvedilol), antiarrhythmics, antidepressants (e.g., nortriptyline, fluoxetine), antipsychotics (e.g., haloperidol), and codeine. CYP2D6 has enormous genetic variability, with more than 75 allelic variants.


So there are about 7% that are poor metabolizers (these people will likely have adverse affects to a normal dosage) and about 6% ultra rapid metabolizers (these won't respond much at all). There is also a good portion of the population that are intermediate metabolizers, who are slightly slower than the majority of the population. Luckily most drugs that are usually metabolized by this enzyme will be metabolized by another enzyme, although more slowly.

Bottom line ... save yourself a possible 3 or 4 days from hell, and go with a low starting dose just to make sure you don't react badly to dextromethorphan.

The general rule of thumb I've heard once you've tried dex at least once is never to try more than twice as much as you ever have before. I would go with about 1.5x as much until you find the correct dosage to get you to the desired plateau. Too much DXM is very much not a fun time.

Once when a bit younger I bought a bottle of muscenex (sp?) at the CVS, and after scrapping the DXM side of the pill into a big pile (something like 15 pills worth) I did a few lines (yes BUUUUURRRNNN) like I said when I was younger, smoked a good ammount of it in my, now dubbed DXM pipe, cut with a bit of weed. and continued to dose my self for 2 days. By the following night I was sitting in a car, and clowns were talking to me as well as tree's immulating dinosaur's. Good time, no need for a repeat. I guess take less then that lol.

i took 600mg with him last night but we both went home before the trip went home so we did not trip with each other. but i was insane vary vary fun. i would recomend a higher dosage if thinking about doin it. because yesterday i first took one bottle of 20 so it was 300mg. then after i was done with that trip i later took 2 bottles so 40 to equal 600mg.

Surprisingly no. Well everyones different but i actually feel more sick on an empty stomach. But ofcourse more absorb resulting in a better trip. And I happen to like feeling sick for a bit because then I appreciate the trip more when the sickness goes away.

I took 120 mg my first time, and slowly worked my way up to 1250 mg. I was not prepared for the trip at all. It was in the middle of the night, I was a sophmore, I snuck out and stole my parents car and picked up a bunch of my friends. Then i got to fucked up to drive, had a friend who was tripping on less dxm drive me home in my parents car and i went into my room and heavily hallucinated all night. It sucked.

The only reason I ever did DXM is because i was restless and didn't have good connections and had nothing to trip on. I don't see any reason why i would ever do it again. I am curious as to how many people who like dxm have had a seperate experience with a different 'good' psychadelic. Shrooms blew me away.

The only thing that can make a dxm trip good is weed. Lots of weed, and no parents if your a minor.

I have a hard enough time remembering what happened on 600 - 800mg range. How do you remember your trips up to 1200mg?

dtasrt_lk
17-10-2006, 13:18
Yea thats a pretty heavy dose. But weight has something to do with it aswel. I only need 600-800 to get where I want to be and thats 11-12mg/kg. I dont think I can keep any more syrup in my stomach lol.

You can build up a tolerance too

skahead17
17-10-2006, 13:24
i dont think i could ever drink the syrup. i take the pills. when i was littl eand my mom usd to give me cough syrup, icould never drink in i would always gag, so therefore i just cant do it. the pills work fine for me, and plus they are more Mg than the liquid.

dxm may change one's perspective on life, but it's different from other psychedelics because it's "not for everyone," as most people say.
for my part, i've enjoyed dxm at high doses, and it can be fun at low doses as well, but you'll have to find the right mix of different substances.

i read on erowid that dxm shouldn't be downed more than twice a week (and that's probably pushing it already).
my experience has led me to believe that it has a long half-life (~1-2 days). on second mornings after i take even a low dose, my pupils are still dilated, and they stay that way till somewhere in the early afternoon.

I can remember a lot of it. Everything I posted happened while i was coming up. I got home near when i peaked and just layed in my bed having the strangest CEV. I think the reaction to doses varies GREATLY from person to person, because 600 mg is a mildish trip for me, and one of my friends claimed after 5 hours that he thinks he might have felt something after taking 800 mg, and another of my friends always took 400 mg when he tripped and would have strong CEV during school (haha) and an aquaintence of mine takes whopping 2500 amounts and loves it.

You should tell your friend/acquaintence that 2g is getting pretty close to the LD50. I wouldn't want another sensationalist news story about DXM.

For some reason my pupils never get dilated on DXM. I dont know why, they get dilated on everything else. Although they did the first and second time I took DXM but that was only 300mg both times.

Me and my boys Zack and Trev we're planning on dropping some DXM the only thing is my bro Zack has a very low tolerance for DXM and when he did 600mg he started to scare me. He started speaking in tounges and getting extremely homosexual. He advanced on Trevor and stroked his c()ckk he then tried kissing him but Trev pulled away. Trev had just been to the tanning booth earlier and if saliva touched his skin it would fade away. I had to control Zack by sucking on his nipples so he wasn't so damn crazy, I then put on my yellow hollister jersey and my hooka shell necklace and ran off into the ocean, out there I floated in the water and thought about dropping DXM I came to the conclusion that after my bro hooked me up with amanitas I'd be down.

Back in the day when I did DXM (called it robo-tripping then) I would just get a few bottles of Robitussin and suck em down, didn't find out til later that there were pills you could take (teenage stupidity I guess lol).

To this day, I cannot take any kind of cough medicine in syrup form, thanks to a summer of drinking the large Robitussin bottles. For those of you that don't know, a stomach full of cough syrup feels TERRIBLE, chugging it down is even worse, and guaranteed puking. The higher plateaus were awesome though, and I don't regret doing it at all.

In the house I lived in back then, my room had a semi-attic attatched to my closet. I call it a semi-attic cause it wasn't above my room, it was beside it. Anyway, it was pitch-black in it, so I spent many a DXM trip in it. The one trip I remember the most, I spent 3 hours in that attic. DUring those 3 hours, from my perspective I was literally looking down on reality holding those crosses with puppet strings hanging from em (I forget what those kind of puppets are called, starts with an "m" and I'm too lazy atm to look it up lol) controlling the movements of all the people I could see. Was an incredible experience and so vivid and lucid that I forgot a few times I had taken a drug and I literally was the controlling force behind everything. Really wild experience lol.

Anywho, be safe and have fun :)

Why dont you kids learn to do a simple extraction for the dxm instead of bitching about drinking syrup or eating 40 pills. You can get all the shit you need at any national chain store. Recipes are on erowid.

Cause the last time I did it was 13 years ago when I was 16 and living at my parents house (and erowid didnt exist):P Of course, if I were to do it now I would extract it (especially since my brain has learned a thing or two since then ;) ).

smoked a good ammount of it in my, now dubbed DXM pipe, cut with a bit of weed. and continued to dose my self for 2 days.

i wasnt aware it could be smoked.

It can't. 4evertweakin was awfully reckless by just going ahead with doing something without any knowledge on the subject.

Smoking DXM is POISONOUS. Don't EVER attempt to smoke DXM. No hbr, no freebase, NONE of the different forms of DXM should be smoked.


Smoking DXM:

Dextromethorphan reacts with oxygen at room temperature, though not at any appreciable rate. However, at 395-397 Kelvin, Dextromethorphan Hydrobromide's melting point, this changes and Dextromethorphan reacts with oxygen to produce some very toxic chemicals. Free ("freebase") Dextromethorphan will also react with oxygen at its melting point. Anyone attempting to smoke Dextromethorphan in the presence of oxygen under normal atmospheric conditions will only end up inhaling nasty compounds such as nitric oxide and the organic products of combustion. This information is easily verified by looking at a Material Safety Data Sheet for this substance. Dextromethorphan reacts rapidly with oxygen at temperatures above 360 Kelvin. It is in everyone's best interest to know that Dextromethorphan is not "smokeable".

My friend is very knowledgeable about psychadelics and drugs in general and probably knows way more about DXM than most people on this forum. He's not just a dumbass chugging tons of syrup to 'get uber fucked up'. He knows very well what the LD50 is, he's just a big guy, has a tolerance and likes to push himself. One of the nicest people i know.

What has him being nice got anything to do with it? And you say he has a tolerance? How often does he take it to have developed a tolerance? You also state he likes to push himself? How can that be knowledgeable?

It doesn't exactly sound like a description of the brightest of people. Or maybe he is, but hasn't quite figured out yet that it's not healhty what he's doing. Even though you believe he knows more than most people on this forum, tell him to read some more on the subject.

I use to do DXM wayyy too much. I did it pretty much everyday for 2 weeks straight. I was pretty dumb about drug use back then, but I pretty much killed the whole dex thing for me. I cant even take a few of the pills without cringing, and I always throw up from it now.

My highest dose was 1400MG with way too much weed. I blacked out and dont remember very much at all from that night. My first high dose was 1200mg...and it was amazing.

I think its a cool drug to use every once in a while, but not an everyday drug abuse type of thing. I was lucky and didnt get any real bad side effects, and im fine today. Its not for everyone though.

In regards to the guy who took 2500MG...yeah that is sort of a high dose, but it does depend on how long you have been doing it with tolerance, and how big the guy is. I wouldnt remember a 2500MG trip so its useless to me anyway.
