Going to try DXM, need tips

Well, me and a friend this Saturday are going to try DXM, with Robitussin. I heard a good dosage is 300mg, but just wondering what you guys have to say about this? Dosages, things to know, general information etc. Also, do you get carded for trying to buy it?

Thanks!

edit for additional questions: As far as that enzyme deficiency stuff, is it really that important that I do a low dose first? I really would like to try a regular DXM trip. And some people say 2 bottles which I'm assuming would be like 600mg, so that wouldn't be a good idea for a first time?

And really, the acetaminophen in Robitussin can kill you? But it's in a ton of pharmaceuticals and people take a ton of it?

Your first dose should be no more than 100mg, you need to test for enzyme deficiency (some people lack the CYP2D6 enyzme that is largely responsible for metabolizing DXM, and they will get more intoxicated for much longer periods of times from any given dose). If you've already established that you're not enyzme deficient, 300mg is an acceptable starting dosage, some might advise you to go lower though.

Also, do you get carded for trying to buy it?
Depends on what state you're in, and the store/store clerk in question.

Oh, and be sure DXM is the only active ingredient.
 
I have been carded for buying it. But I think there have been a few times where I haven't been carded. You're supposed to be 18 to buy it. I would agree that about 300 mg is a good dose for your first time. Get maximum strength robitussin. One 4 oz bottle is around 300 mg, slightly more if I remember correctly. It should give you a decent second-plateau trip.

The important thing is to make sure the cough syrup you get has ONLY DXM as an active ingredient. Guaifenesin will make you throw up (if the syrup itself doesn't). Other active ingredients, such as acetaminophen, could kill you.

For more information, check out erowid's dxm FAQ:

300 will only reach 2nd plateau, which is very dissociative and not very psychedelic. Not much of a trip, more similar to being drunk.

Agreed. My first DXM trip was second plateau. Having nothing else to compare it to, I described it as being drunk and high on cannabis simultaneously. However, I wouldn't recommend going any higher than second plateau for a first DXM trip, unless you have experience with other disassociatives (K, MXE, PCP).

Yes it is important, if you are enzyme deficient, your 300mg will hit you like several times that dose and could last for days, it's dangerous. Only a very small number of people are deficient, but an ounce of prevention is worth a pound of cure, as Ben Franklin put it.

600mg would not be a good idea for your first time for the simple reason that only a minority of people who try it actually like the drug enough to take it again, with many actively disliking it. Even if you have dissociative experience it's no guarantee you'll enjoy this, a second plateau dose will give a you a feel for what the drug's about and if you want to push it further into the higher plateaux.

If you haven't read the FAQ or other material, you definitely should (and I feel you haven't, given these inquiries). Best know as much as you can about it before jumping in.

~450 people die every year of acetaminophen overdose in the US, and plenty more experience liver damage from it. It's no joke, get DXM only syrup!
 
Enzyme deficiency?

I think you guys mean multiple copies of the enzyme, aka CYP2D6 polymorphisms, which is the opposite of a deficiency. DXM acts a prodrug to Dextrorphan (DXO), a powerful NMDA antagonist. DXM is converted in to DXO through O-Desmethylation, as is codeine to morphine and tramadol to O-Desmethyltramdol.

If you are CYP2D6 enzyme deficient, you would not convert enough DXM to DXO, making DXM useless as a dissociative; you would just feel the 5-HT/NE effects off of DXM and wouldn't robotrip. If you are a CYP2D6 normal metabolizer, you will have regular effects. If you have CYP2D6 polymoprhisms, you convert a much larger amount of DXM in to DXO, so the larger amount of converted DXO means you trip harder and longer, as it takes longer to eliminate a larger amount of drug out of your system.
 
^My phrasing was off. I meant to say deficient individuals have been described (everywhere I have read) as experiencing overwhelming effects from small doses, and they last for a very long period of time, and persons with this condition have still used the term trippy to describe effects. I did not mean to say that those effects were primarily dissociative/NMDA related.

More DXO would be desirable afaik.

For DXM, always have some benadryl or another antihistamine ready in case you need it. You might break out in terrible hives. This usually happens during the first DXM trip (if at all). Scratching until you are about to break the skin while tripping really hard is NO FUN. The benadryl can also help you get to sleep later. If you are worried about being completely dissasociated at some point, make sure you only have a few of the antihistamine pills around.
 
I agree with the others, keep it low for the first time. My first time i only had about 250mg but it had me high as a kite! And benadryl is very helpful for the robo-itch which can be a real hassle, just dont take so much benadryl as it will knock you out. Or at least it does me. Sometimes I would get real hot and itchy and my chest would get like red and splotchy or whatever its called. Not hives but small red spots everywhere that were itchy as hell.

Also, for future reference in case you become very fond of DXM, do not attempt sigma unless you really are in good healthy condition and have a stable head on your shoulders.... but even then it can still screw you over pretty hard. Just advice from someone who still isnt all the way there after an ambulance ride to the ER.

Stay safe and be smart! Don't underestimate the power of DXM.
 
600 mg for a first trip is a bad idea for the above reasons, and others. I can consistently get 4 oz of syrup down without much of a problem. However, 8 oz inevitably results in either vomiting or explosive diarrhea. Even after throwing up, you can still trip pretty hard. At doses that high (assuming you're of average weight), walking will likely be very difficult, and speaking will be near impossible.
 
I have never vomited from DXM, syrup or powder. No diarrhea either. The closest I've ever came to vomiting is slamming a can of Sunkist to get rid of the taste and then throwing up foam.
 
Oh my god. Please don't jump straight from an enzyme deficiency test (~100mg) to 600 mg. You need to begin with 300 mg, and increment your dosage by about 50 mg, no more than 100 mg, with each successive trip.

600 mg would be a hellishly intense overdose for me. 390 mg DXM HBr was absolutely my maximum limit, and I'll probably never dose that high again -- it was incredibly bizarre, disorienting, confusing, and overwhelming. Although admittedly, extremely interesting.
 
Be careful with dxm. it's more noticeable u took it than acid. at 1st plateau ya eyes go really open & ppl with think ya on speed or something. at 2nd they will think ya drunk & stoned. I took it a few times about 8 yrs ago
 
I looked it up and all of the Robitussens I found had that gua- chemical that makes you puke.

What's the exact Robitussen to use?

Thanks!
 
Just look at the box of each kind of syrup (or pills, sometimes you can find robo gelcaps, but not many places carry them) until you find one with DXM as the only active ingredient. Pharmacy/convenience stores chains are more likely to carry what you want than a big department store with a pharmacy section IME.
