I would like to know the similarity, and differences between the two.
I know very little about Phenobarbital but know a fair amount about benzo's.
I want to know the pro's and con's of each different drug. Any input would be appreciated, Thank you BL in advance.

The difference is that phenobarbital sucks. I love barbs, but pheno literally has no recreational potential unless you find sleeping particularly euphoric. Secobarbital, pentobarbital, awesome drugs. But pheno will do nothing but make one drowsy, not unlike taking a couple Benadryl. There's a reason pheno's so available compared to other barbs...

If you use the search engine, and maybe google "barbiturate" to get some general info on the drugs (most barbs feel pretty similar I think, at least the few I've tried, just like how most benzos have very similar effects), you could probably come up with your own list.

The main difference that I will state is that phenobarbital is much more dangerous than any benzo. This is because it is possible to overdose on phenobarbital even if it is not combined with another drug. The LD50 for animals is given at 165-200 mg/kg^-1, which I think yields a lethal dose of 1200-1400 mg for a 150 pound (or 68 kg) individual, although my math may well be off...if someone better at numbers can correct me please feel free.

Benzos, on the other hand, are nearly impossible to overdose on IF AND ONLY IF they are NOT combined with other drugs; mixing benzos with opiates, alcohol, and other CNS depressants make overdose an incredibly simple phenomenon.

I think this should maybe be moved to BDD since its not exactly a specific question on a single drug, plus I am thinking this topic may have been covered in the past.

Bump! experiences anyone? ualways thought it wasnt "bad". Always just hear from people who dont take alot, how is it in much higher doses, nice sedation? whats the feeling like, idc if it isn't as good as valium, xannies , etc which i already realize. But is it alright? :) . I always see a few who love it

Benzos are much better IMO, phenobarb will just knock you out completely and if it doesn't you won't remember wtf you did on it. Not you could do much but be a zombie on it though

600mg seems to be relaxing(taken over the course of 8 hours),sedating( not too tiring), Definately posses's hypnotic properties but nothing like a moderate dose of xanax,lorazepam etc. Alot m ore clear headed than benzos . always figured pheno would feel heavier . Surprising....Barbs are an interest atm.

Would a benzo tolerance affect a barb tolerance? May seem like a stupid ? but have no idea. the ld50 is somewhere around 1300mg or something? that can't seem right? Benzos and low dose of phenobarbital taken together can definately slurr you out bad. I don't want to set myself up here , but is this barb scare a bit over rated? alone it seems it won't wreck you like bennies, maybe its deceiving the user

What's a lethal dose of pheno? I only have like 4 68mg pills, and 1 clonazepam 1mg. If taken together will I first of all be okay, and second of all feel a buzz. Will pheno synergize well with the clonazepam?

i agree phenobarbital is boring and even uncomfortable by itself, and it lasts a couple of days. expect to feel gloomy and dysphoria. i have mixed pheno (90mg) with tramadol (600 mg) valium, (12mg), and dozy (25 mg) (i know dangerous). i don't vouch for this, but i will share that it feels like ecstasy and like i am walking on air. i do avoid sleep though and try to stay alert fearing the synergy effect. i do have high tolerance to all three, especially trams, but not phenobarbital. i have slept and woke up. it was such a comfortable sleep like ambien but longer. but again, this is playing with fire. not much experience reports on mixing pheno and benzos. anyone experience this?

Komatose : i believe phenobarbital lethal dose depends, but it can be fatal as low as 1 gram. the most i took with valium in my system was 240 mg. it was uncomfortable and told myself not to do a high dose like this again. yes, there is a synergetic effect when mixed with a benzo, but the lethal dose may be even lower for pheno ... so be careful. i have mixed klonopin with phenobarbital, but just found it sedating without any euphoria. i believe it was more comfortable perhaps because the dose was modest and the klonopin made it smoother. i am even paranoid taking less than 100 mg of pheno -- 60 mg or less i am very comfortable and enjoy without the lingering thought i may die. for christ sake, people use phenobarbital to commit suicide (e.g. Heaven's Gate Cult), although clearly other rare barbiturates are more dangerous or effective with suicide if desired. i believe tramadol and pheno is an unbelievable combination. its a pseudo-MDMA high (tramadol, albeit not for everyone ... but i'm lucky i never get nausea on high doses). in addition, the pheno prevents seizures. but again, this is risky business mixing. even if death isn't a strong possibility, you may be gambling with your kidneys and liver. be careful with ANY barbs, including the boring phenobarbital. be safe and happy trippin

interesting. i guess i am sensitive. my benzo tolerance is very high (e.g. 120 mg of valium, 8 mg of xanax, etc.) of course i am pretty far gone, but not like passed out the entire time. fragments are only remembered. i figure 40 mg of valium is a maximum comfortable dose where i can function practically normally, or so i think in my head. i think its tolerance independent because pheno works on different receptors on GABA. hence, tapering off benzo using phenobarbital is no longer recommended -- in fact, it is considered barbaric. i did hear barbs are cross tolerant with a benzo like midazolam. i found the pills very boring taking up to 120 mg within 30 minutes. i could swear that i'm getting difficulty breathing spells though when i mix pheno with benzos and trams, and even over-the-counter sleeping pills. it could be the profound poly effect. 600 mg of pheno is way too much for me and i wouldn't do this because i would be so uncomfortable. i can forget working or even walking or talking coherently for awhile. more like watching tv like a zombie for 5 days with major depression. yup, i get that heavy feeling too which does suck IMO. good to hear feedback on phenobarbital as i have a general fascination with barbiturates. not sure why?

As a kid, I used to take a med called Quadrinal for asthma. It contained theophylline, ephedrine, potassium iodide and phenobarital.

The phenobarbital was part of that concoction to calm down the shakes you'd get from the combination of theophylline and ephedrine, both strong CNS stimulants.

It felt like a screwy speedball and left you drained.

AfterGlow : did you ever have panic attacks? did you feel heart pains? that combo (regardless of dosage) seems crazy. and this was for helping asthma? was it the spray, or was it pills? sorry, i don't know much about asthma except for some people that have the condition. interesting to hear a barbiturate is assisting with breathing, or maybe its for the "shakes" -- i can understand that

Yes, I used to suffer from awful panic attacks. I'd go into crazy temper tantrums too.

Back then, they didn't have all of the corticosteroids for treating asthma. So strong stimulants were used for their ability to relax smooth muscle and open up airways.

Quadrinal was a pink horrible tasting liquid. The pheno in it was not to help the asthma. It was to help with the terrible side effects of the strong stimulants.

The (shitty)thing about phenobarb is that it has a LONG half life its easy for you not to feel any effect immediately and decide to redose. Big mistake esp if you combine with other substance. IMO short acting barbs are better if not safer Oh and the above info is from personal exp a phenobarb and codeine binge that almost turned fatal.

i emphatically agree. the phenobarbital half-life carries over and that can accumulate shortly to a potential overdose. knowledgeable warning!

Iv'e done phenobarbitol a handful of times and benzos a crapload. I MUCH prefer just about any benzo to phenobarb. Phenobarb gets a bad name because you have to take a ton to feel anything, and then your only high is feeling medium level drunk for 10 minutes then falling asleep. IMO phenobarb is pretty worthless as far as recreation goes.:\

yup, and dangerous too. that's why they give to dogs. it was just interesting to note that mixing pheno can produce a quality high, but the risk is probably not worth it. do you know how much pheno can accumulate in your system? ex. if you take 120 mg pheno for three days w/ other substances (benzos, opiates in fairly high doses) -- are you in serious danger?
