Pot-smoking style linked to addiction risk

By C.E. Huggins NEW YORK (Reuters Health) – Marijuana smokers' behavior is more important than the potency of their pot or how much of the psychoactive ingredient THC they take in for predicting who will become dependent, according to a small new study. Researchers have debated whether smokers of high-potency cannabis varieties are at greater risk of addiction because they get more THC, or if they compensate for the pot's strength by using or inhaling less of it. But it's their style of pot smoking that predicted who was most likely to become dependent. Most previous research into cannabis dependence has looked mainly at how frequently a person uses cannabis, Van der Pol and her team note in the journal Addiction.
