Started smoking weed when I was 14 on and off, by the time I was 18 I was either smoking with people I couldn't connect to or smoking alone. My brain didn't like those conditions, used to think up some really horrible shit and at one point had a knife to my own gut with the idea of killing myself. I remember my dog coming in the room and looking at me with the most puzzled look on her face, so anyway I fucked the weed off instantly then.
I became very anti-weed for years, especially to younger friends. I was very much a dick to everyone who smoked it. There's a lot to the dangers of smoking cannabis before your brain is fully developed though.
I'd cooled down by the time I was 21 and tried MDMA for the first time. Since then there's been periods where I've been on it far too much, I remember we'd go out for drinks and all we could think is... well this could be a lot more amazing if we had some MDMA. Back then the MDA/MDMA lovehearts were £3 a pop it made no sense to booze up. The comedowns though man, fucking hell.
Almost 30 now and I believe I've found the balance, probably have a bit of a sesh every two months and maybe smoke weed once a year with close friends. It helps not being arsed about going out to the pub every week, honestly I have a great time gaming with my friends or hanging out.
