What was your weed laced with if your after effects are anxiety depression blurred vision paranoia lack emotion eg: cant laugh at things that are funny and how long do they last? or are they in your head
You are only young and looking for answers, we all were at one time, it is doubtful a one off experience with weed, laced or not is your issue. You have mentioned bereavements and that is more likely to be preying on your mind, try to find an understanding relative or failing that a GP, wish you well.
Damax....he's said he's used it once 5 months ago.
Normal weed is known to make you paranoid if you use it on a regular basis. Skunk is a different matter and has been known to cause serious mental health problems from just a few uses.
I was corrected by 2 friends of mine who use this 'shi!t' daily, one works, one is on benefits and they can afford this stuff everday (somehow), apparently it is now called 'green'....LMFAO !
