Someone in my family, complete drop kick who you can't even hold a conversation with anymore. Now they have issues with anger and mental health.
All thanks to weed, which many people will preach that it's not addictive or harmful.
Try telling that to them, they wake up before work and smokes 10 bongs and then another few at work and then as many as they can before bed.
I still remember the day they told me "everything is alright in moderation"
