Yeah miv you're absolutely right, anything is dangerous when you think about it. After all, "safe" or "not dangerous" is merely defined as "the absence of risk". So, what then is "safe"? Of all the psychoactive substances, cannabis is the SAFEST, least physically addicting, and most able to be used recreationally. Drugs like cocaine and crystal meth cause psychosis and schizophrenia, due mainly to increased dopamine activity resulting in chemical inbalances, muthafucka.
