Found this list on The Fix of the hardest drugs to kick....
Not shocking that Heroin is #1 on the list... knowing some of the symptoms and reactions that these drugs costs don't seem worth it to me... I will never understand it.
1) Heroin
2) Crack Cocaine
3) Nicotine
4) Methadone
5) Crystal Meth
6) Alcohol
7) Cocaine
8) Amphetamines
9) Benzodiazepines
10) GHB
