The way I read the articles is that weed CAN be addictive in a relatively small percentage of people. The perspective I took when reading it is comparing the language used to describe alcohol addiction or crack...the language used is much different, such as, if used to much you WILL become addictive. Out of all the people I know who do weed (smoke or edibles), which is a lot, none of them has ever felt addicted to it. Alcohol on the other hand...bad bad bad.
When all is said and done, if my kid decided between weed or booze as his vice, I'd sure hope to hell he chose weed...of course hopefully he chooses neither.
