It depends on what your tripping on, shrooms and lsd weekly isnt bad for you at all but tolerance builds up therefore tripping weekly is seemingly impossible after a while and mostly after first time tripping you must wait a month for same effects with same doseage, as for E, yes its bad for you if you've been tirpping weekly since December, take a needed break my friend. that is unless its pure MDMA but even then its reports show significant results of some damage to your body especially as abusive as it sounds you are. take it easy and hope this helps.
