Good advice this ,I was the same at that age a proper pot head my mum didn't hit the roof she talked to me like an adult talked about the other things like heroin and stuff .i gave up at 21 not touched it since my uncle on the other hand said my cousin was pushed into it and blamed everyone but him , it was everyone else's fault when he nicked his credit card ,the same when he got caught dealing weed then coke then everyone else when he was a full blown coke head . It was still everyone else's fault when he remortgaged his house to pay for rehab
