Don't comment on things you have no experience with. Chronic users of Marijuana may feel a lack of desire to do things. But, stop generalizing Marijuana smokers. Many smokers smoke on occasion or just a few times a week and they show no lack of desire or motivation. This is like saying all white people are racist. Its highly ignorant and you should feel slightly embarrassed. Prescribed medications are hard on your body, can be addictive, and can do more damage then good. Marijuana in moderation will do nothing but good things for you. Unless you have asthma. Don't do it if you have asthma.
