Marijuana is the third most popular recreational drug in America. Around 100 million Americans have used marijuana, and over 25 million used it in the past year. Marijuana is less dangerous than alcohol and tobacco, which collectively cause over 400,000 deaths per year in the US. Marijuana does not cause fatal overdoses and is nontoxic. However, marijuana does have negative effects like forgetfulness, lack of concentration, and dizziness. There is debate around legalizing marijuana for medical uses to treat conditions like nausea, pain, seizures and muscle spasms.
