Chances of overdose on marijuana are extremely small. While this drug does not cause the same sort of life-threatening symptoms seen in the overdose of other illicit drugs, it is possible to suffer adverse effects if large amounts of marijuana are used.
Increased use of marijuana, combined with lowered perceived medical risk of use, has led to questions about the long-term and short-term effects of the drug. According to NIDA, marijuana is the most commonly used illicit drug. In 2013, marijuana was used by 81 percent of drug users, and 65 percent of drug users reported that marijuana was the only drug they used. Marijuana use is especially widespread among adolescents and young adults.
Effects and Risks of Marijuana
The effects of smoking marijuana are typically felt almost immediately. Ingesting the drug will usually delay the onset of the effects; you may begin to feel them 30 minutes to an hour after eating or drinking the product. This method of ingestion delivers less THC – the active component in marijuana – into the bloodstream than smoking the drug. Effects felt from smoking generally last 1-3 hours, while effects from eating or drinking can last for several hours.
