Indeed, there are a number of myths about marijuana, and not everyone experiences this drug the same way. However, there is a growing body of research to indicate what the potential benefits and drawbacks are of marijuana use.

However, some individuals may also experience a rebound effect of increased anxiety after the drug wears off. The fear of getting caught and charged (depending on the laws of where you are using marijuana) may also increase the stress in some marijuana users. Some long-term users have been found to have increased difficulty dealing with the stresses of day-to-day life. 2 Myth: Marijuana Makes You More Peaceful Deux/The Image Bank/Getty Images Marijuana was promoted in the 1960s as being the drug of love and peace. While weed does often temporarily subdue users—and can even decrease energy and vigor after long-term use—it does not necessarily reduce aggression. In fact, smoking marijuana may increase anxiety and paranoia in some susceptible people.

Smoke inhalation of any sort is harmful to the lungs and may increase the risk of lung cancer and other diseases of the respiratory system. Unfiltered smoke is particularly harmful. Marijuana use has also been linked to certain mental health problems and the risk increases the younger a person is when they begin using marijuana. 5 Myth: Smoking Marijuana Is Healthy Because It's a Plant, Not a Drug Mikhail Meleyev / EyeEm / Getty Images There are many poisonous and hallucinogenic plants that are unhealthy for human consumption. Several drugs including weed, heroin, cocaine, magic mushrooms, and alcoholic beverages come from plants. Consuming them still comes with health risks. The important thing to note is that there will be no "cure-all" effects of any one drug. Even for those who experience relief with marijuana, there are potential drawbacks to any drug consumption. It is best to take any widely held beliefs about any substance in moderation and to remember to act with your overall health in mind.
