It's going to be people in their 40s and 60s and 80s who find they prefer a little marijuana to that drink in the evening or the sleeping pill or that it helps with their arthritis or diabetes or maybe helps spice up a long-term marriage.  And that just might be a net public health benefit.
大概40多岁、60多岁 和80多岁的人，他们发现自己宁愿吸点大麻 来代替晚上喝的一杯酒或者吃的一片安眠药 或者是用它来舒缓他们的关节炎或糖尿病 又或者，用它来给老夫老妻的婚姻生活增添点情趣。 所以这对公众健康或许也有一些益处。
