Well, he isn't wrong necessarily. At least relative to what is legal in the U.S. I mean, cigarettes are one million times worse but an unsavory amount of people smoke them. Not to mention, marijuana has plentiful uses in manufacturing environments. In fact, the reason marijuna was made illegal was because it was about to take over the logging industry (for paper). But, the giants of logging created a giant array of smear campaigns and got marijuana shut down. Marijuana isn't addictive*, it can help with many things including Glaucoma. Plus, if the government were to utilize the demand for marijuana and tax it, it would create a giant influx of cash into our economy.
