From personal experience susceptible people get paranoid schizophrenia like symptoms with cannabis use immediately, which should be a warning. From a scientific angle there are statistic links, but not a proven causal link.

Truth is, you probably should not do it, but likely it’s not going to wreck you either. Nobody knows for sure what will happen to you.
