I think q' it would be necessary to authorize drugs because although she are bad for our health, traffics of drugs and his trade make more death than the drug substance.
Making it legal will just make things worst ! There is no way authorizing drugs will solve the problem of the drugs in the country ! If that happens I dont think what the world will look like be . I am not against legalising it for the sake of making it as a medicine but other than than there should be no reason at all to legalize it
