Hey, I see where your coming from man.

I smoke weed pretty much every day (with some tolerance breaks). I do MDMA every month/two months, used to do MDMA and abused it badly for about two months but I learnt to stop and control it. Learn when to stop and say no. If these substances effect your mood/emotions and it is making a significant impact on you, stop all of it (Weed is usually fine to do regurlarly unless it has a big effect on you)

Just think that you are in control not the drug!
