Research shows that individuals who start using marijuana during their teenage years are more likely to develop a dependence on it as adults. Additionally, David's peer group's continued use of marijuana is likely to reinforce his own use and make it more difficult for him to quit. Therefore, it is likely that David will increase his use and dependence on marijuana in his 20s.
