I recommend shooting a quarter gram of crank the first time you ever try it. If you don't die, I'm fairly confident you will steer clear of crank, and that's a good thing, at least. 

the amount of shrooms you should take for your first time is an 1/8 of an ounce because 1/16 you prolly wont actually trip
Temaz has recreational value? :S

I have a new found respect for benzos from last week. Nothing serious happened; previously I could take 22mg (diaz) and have a good time, this time a mate and I took 25mg and ZONKED. Woke up an hour later like wtf!?! lol.
Be safe.
I weigh roughly 100 kgs and wonder how much codeine I would need (no opiate tolerance) would 100mgs do?
Erowid said:Again a good dose to start using codeine at is in the 30mg to 60mg range. At this dosage range the adverse effects tend to be minimal, and the pleasurable effects quite noticeable.
[I have never noticed any euphoria below 100mg, so don't give up just because two 3s don't give you a high. *However, some unfortunate individuals are allergic to codeine, and, if you have never used it before, first try a dose of around 30-60mg and see what will happen. It is dangerous to start off in the high dose range.*]
