My darling brother is now 25 for the past 7 years he has suffered from cannabis pyschosis. He has not touched cannabis in last 7 years. He smoked it occasionally as a younger teenager and then heavily for about 6months and that was all it took to change him beyond recognition. He didn't respond to any anti- pyschotic med except clozapine which basically got my brother mostly back and normal. Unfortunately this med is also evil and my brother has had a minor heart attack (a side effect of meds) so they have had to take him off it. This has caused a major relapse and he is currently hospitalised. It is a rock and hard place situation- keep him on the only med that allows him to function as a human but risk him dropping dead of a heart attack.
My brother didn't realise the dangers of cannabis misuse and from speaking to many drugs workers they actually find cannabis the scariest drug- because of it's terribly harmful effects and the fact it is so prevalent. And these guys work with crack addicts so for cannabis to be scarier that's a big deal!
Please talk to your teen about cannabis, it isn't the harmless happy high drug any more. Variants now are so much stronger and have power to permanently alter your brain. Studies have found those most at risk is young men under 25.
I can honestly say that drug has ruined our families life and it terrifies me how many other lives it is ruining by this perception it isn't a dangerous drug. It really is.
I will never get my little brother back completely and at the minute we don't know what is going to happen with him but I had to post in the hope that it may help someone try and prevent it happening to someone they love.
