go with acid man coke aint bad up front but the ride is really short and if you get doing it your going to get alot of fucking side effects. Acid doesnt hurt your body at all and it lasts a really fucking long time. Of course if your in a bad state of mind or going through some trouble in your life thats digging in to you dont do acid cuz it seems to usually aluminate what your trully feeling. Also if you never done any hallucinogens of that kind of strength then dont do to much your first time maybe half a paper if its good stuff if its crappy go with a whole papper. Stick to lsafe drugs and you will be rewarded in Odins hall. jk bout the odins hall
