My anatomy class is learning about this, and I am not sure of the answer, and neither is my teacher.Got an answer for me??

[C N]

its not.. heroin is massively more addictive

[Kal-El]

Marijuana is not more addictive than Heroine. That is just crazy. Marijuana however is easier to get and cheaper so more people do it regularly.

[jellybeanchick]

I have never heard that. Heroin is one of the most addictive substances; only a few others (like tobacco) are more addictive. Marijuana has some potential for addiction, but not as much as heroin.

If your teacher said that, then he/she is clearly an idiot or is lying on purpose.

[James M.]

Heroine is way more addictIVE! Not marijuana. Your teacher must be an uneducated dolt. Sorry, idiot for those dolts who don't understand. :-)

It's the other way around. Heroine, as well as many other opiate drugs, stimulate a reward pathway in the brain that undergo very rapid adaptation to the drug.Opiates, of any kind (even Codeine), are very addictive. Even short courses of them can have noticeable withdrawal symptoms.
