Common Marijuana Side Effects

  • Side effects of marijuana include red eyes, dry mouth, increased hunger, nausea or vomiting, lung problems, depression, flashbacks, panic and problems with sexual function.
  • One of the main side effects of marijuana is a "high" feeling, which may be described as a state of euphoria. The high derives from the chemical THC found in marijuna. The side effects of THC can include impaired thinking and hallucinations. Marijuana may also cause problems with memory and learning for weeks after consumption.[4] Marijuana affects the ability to drive safely, and as with alcohol, operating a motor vehicle while under the influence of marijuana is a punishable offense.
  • Marijuana leads to reduced fertility in men, which may occur if the man or the women use it, as it can be passed on to sperm via vaginal secretions. Men who have low fertility to begin with may be rendered infertile with marijuana use.
  • The risk of heart attack is more than quadrupled during the initial hour after using marijuana.[5]
  • Regular marijuana users are more prone to chronic coughing and respiratory illnesses.[5]

Marijuana Allergic Reactions

Just like with most substances, it is possible to have an allergic reaction to marijuana. This allergy can manifest itself either externally or internally, just as with food or other allergies. Some people are allergic to the cannabis leaves, while others are allergic to pollens or molds that may be present within the plant. Some people who do not show allergic reactions to marijuana smoke may react to edibles containing marijuana.

Marijuana Precautions and Warnings

  • Marijuana has been shown to have adverse effects on a fetus, and can hamper growth as well as central nervous system development. In addition, babies of marijuana users tend to have shorter attention spans, lowered ability to concentrate and impaired short-term memory.
  • It is possible to become addicted to marijuana. Approximately 9% of those who use it will become addicted, and this number is higher among those who start to use it in their teenage years. Addicted individuals may experience withdrawal symptoms like insomnia, irritability, lowered appetite and cravings for up to two weeks after quitting the drug.[5]
  • Regular marijuana use has been shown to hamper career success and social interaction.[5]
  • Taking a high dose of marijuana can trigger a temporary psychotic episode, causing paranoid thoughts and hallucinations. Schizophrenics who use marijuana may find that their illness worsens, and healthy individuals who use marijuana may be more likely to develop psychosis later in life.[5]
