The most dangerous drug

The most dangerous drug is methamphetamine usually called crystal meth or just meth. In my opinion, crystal meth is far more dangerous than heroin because once you take one hit of crystal makes you crave it for as long as 20 years. It sends message to your brain that makes you high and feel really happy like you just won a 1milliom dollar lottery for 6hours. This drug is very addictive (one of the hardest drugs to get off of)
