Marijuana is constantly attacked by many politicians, even though use by adults (use by children is a different story) rarely if ever results in a visit to the hospital. This makes me conclude that the problem with marijuana is that users and producers need more expensive lobbyists. I write this based on an eye-popping article on the well-established dangers of LEGAL drugs in the September 2014 edition of Consumer Reports. Here's an excerpt:

OxyContin, Percocet, and Vicodin--prescription narcotics . . . can be as addictive as heroin and are rife with deadly side effects. Use of those and other opioids has skyrocketed in recent years. ... 46 people per day, or almost 17,000 people per year, die from overdoses of the drugs. That's up more than 400 percent from 1999. And for every death, more than 30 people are admitted to the emergency room because of opioid complications. With numbers like that, you would think that the Food and Drug Administration would do all it could to reverse the trend. But against the recommendation of its own panel of expert advisers, last December the agency approved Zohydro ER, a long-acting version of hydrocodone. Almost as dangerous is a medication renowned for its safety: acetaminophen (Tylenol and generic). Almost 80,000 people per year are treated in emergency rooms because they have taken too much of it, and the drug is now the most common cause of liver failure in this country.

Some patients are having astounding success with fecal transplants, and a DIY community is growing. BBC reports:

There is growing recognition that faecal transplant is the best way to treat [some] patients. In the first randomised trial of the technique published in the New England Journal of Medicine last year, 94% of patients were cured by the treatment, whereas a course of antibiotics cured just 27%. The disparity was so huge that the researchers stopped the trial early, on the grounds that it was unethical to deny the better cure to the cohort assigned antibiotics.
