Heroin gets a bad rep. Yeah it'll make you extremely unproductive. But fuck it if you've given up on life there's no reason not to experience pure bliss. In all honesty how dare anyone tell you you don't have the right. Why should anyone else have the right to choose. The potential for pure bliss exists but this stupid society would rather you just die without ever having experienced it. It would rather you lived to old age so you can be a vegetable hooked up to life support.
Heroin is pure, natural bliss. You've been put in this shit society with a shit hand of card. The escape room from all this pain does exist. It is natural. You can experience bliss. Every second you continue struggling against this existence might be a waste. You can experience heaven on earth. Heroin is not even particularly toxic. You could keep up the habit for years without dying.
I'd avoid MDMA though. Really think you shouldn't take MDMA. Or maybe once but repeated use of MDMA will fry your brain and leave you unable to experience pleasure at all
