Did you know that most UNH students (76.8%) choose not to use marijuana? This is interesting especially when the same students surveyed reported that they believe most UNH students smoked (91.3%).  Why?  Often people misperceive how much a substance is being used, maybe because their friends use, or maybe just because it seems like everyone on campus is drinking and smoking, so it seems believable.


  Everyone smokes when in college.  
Most never use marijuana and of those who do use, few smoke on a weekly basis.

Myth.  Marijuana is not addictive.  
Marijuana follows the same pathways of addition in the brain as other drugs.  Signs of physical/psychological dependence?

  • A growing interest to smoke more often.
  • The use of marijuana, or thoughts of using, replaces other things that used to interest the person, including but not limited to:  hobbies, sports, working out, class work, clubs or organizations, friends (especially those who don’t smoke).
  • Less interest in doing activities sober, or not high.
  • Increase in tolerance, needing more marijuana than before to feel the effects.  Putting self in danger (legal or physical) or dangerous situations to smoke.

People are more likely to experience a problem when smoking marijuana on a weekly basis or more often.

Most people who smoke daily experience some psychological and/or physical addiction which can be witnessed by withdrawal signs when not smoking.

Withdrawl Signs

People can experience some or all of these signs if they are physically addicted to marijuana and have stopped using. 

  • Insomnia or sleep disturbances
  • Nightmares, vivid dreams (very real, colorful, etc.)
  • Dreams about using marijuana
  • Irritability and anger
  • Occasionally emotional swings, with or without anxiety
  • Headaches
  • Increased sweating (night sweats, sweaty hands)
  • Coughing
  • Eating issues (loss of appetite, digestion issues, cramping)

Most physical withdrawal signs will pass within 2 weeks – two months, however the issues around psychological addiction can remain for many months for some people.

Help With Withdrawl Symptoms

  • Take hot baths
  • Drink plenty of water and other clear liquids (you may also want to try cranberry juice)
  • Eat foods that are high in potassium like melons, bananas, citrus, green leafy vegetables and tomatoes
  • Decrease fat intake, especially if experiencing stomach issues
  • Decrease caffeine use, especially if feeling shaky
  • Drink warm milk before bed if having sleep issues
  • Exercise


One problem people will often find is that they will abstain from smoking for a while, maybe even 6 or more months, and then will decide they can smoke once, or once in awhile.  Unfortunately, they will often find themselves quickly increasing use to the levels they were at before quitting.  That is how addiction works, once triggered it stays within the brain even when the person has stopped using.

About Cannibis/Marijuana 

Other Common Names: marijuana, “pot”, “weed”, “grass”

Marijuana is the dried shredded leaves, stems, seeds, and flowers of the hemp plant. It is smoked, eaten or vaporized to release its active ingredient, a chemical called tetrahydrocannabinol, also known as THC. It also contains another 400 chemicals, some of which are carcinogenic. Pot is a mind altering drug (psychoactive). The THC triggers the brain cells to release dopamine which is what creates the “high”. The drug is illegal in most states and is the most commonly used illegal drug in the United States, though conversations for legalization for medical use or decriminalization occur throughout the country regularly and have resulted in medical use policy.


Marijuana can cause euphoria, increased heart rate, impaired or reduced short- term memory and distorted perception. It can also cause the reaction time to slow, blood shot eyes, throat and mouth to become dry, a relaxed feeling, and can cause the user to become hungry and thirsty.
