If current estimates are correct, around 10% of users (and one in six who start in adolescence) may become dependent on marijuana – that is, find it difficult to control or discontinue their use. A minority of these problem users will seek professional help to quit.
如果目前的估计是正确的话，大概有10%的使用者（其中1/6在青少年时期就开始吸食）将发展为大麻成瘾——这意味着他们将难以自我控制或者戒除大麻。而其中只有一小部分会寻求专业人士的帮助。
