Bro, you cant use any drug on a weekly basis without experiencing negative side effects and damage, depending on which drug. This includes alcohol and weed too. Cannabis to a MUCH lesser degree of course...
LSD is better than MDMA for this, but of course, tripping every week gets bad after a while too. Same with speed, opiates, ketamine, benzos, GABAergics... ANYTHING.
If you cant go to events without getting fucked up on hard drugs... maybe its time for a break from the scene, eh? Remember, its not supposed to be about the drugs... Try just smoking a LOT of weed, and doing a few shots with it too, and an energy drink or something for some extra stimulation.
We dont do "what should I take" threads here though, so this will probably be closed.
