in my experience most people who do have "bad trips" on weed are pussys haha sorry but its true at least like 90% of them, i mean come on its just weed. I mean i had the panic attack or 2 back when i first started but I mean it wasn't hard to just talk myself down when I know for a fact that weed hasn't ever killed/caused major damage to anyone, and i would never let an experience like that turn me away from weed, i just smoked again and got over it.
