Quoting something you don't understand can make you look smart if the people you are quoting to are ignorant about the topic. Otherwise, you just look like a know it all with limited reading and comprehension skills who can use ctr+c ctr+p
You obviously don't understand what physical addiction means. Cannabis can be psychologically addictive, just like food, sex, or virtually anything.
Very few drugs are physically addictive. Even drugs that have a high propensity for psychological addiction are not physically addictive: Tobacco and Cocaine are a perfect example.
Drugs that are physically addictive include alcohol and heroine as well as many prescription drugs. Those are the ones that produce hallucination, censure, and other such physical symptoms. Such symptoms can be fatal.
To put it another way: Psychological dependance = you REALLY want it bad because you
think you need it
Physical dependance: The tissue in your brain has literally changed, and if you stop taking it, your
BODY (not your mind) will go fucking haywire.
Even the gov understands this, that is why heroin addicts get methadone. No one is giving pot heads who quit fake and low dose marijuana.
