This drug is called the anti-pot and it is meant to counteract the effects of marijuana. It had been approved to be used as a weight loss drug. However, some people who took it became suicidal and depressed, so the drug was taken off the market. It is mainly used to reduce the user’s appetite. It works as CB1 receptor blockers, and it has been approved to be used in over 38 countries, including Brazil, Mexico and the EU. However, it is not approved to be used in the United States.
