Marijuana

How can I tell if my child is using marijuana?

Marijuana comes from the cannabis plant and looks like dried leaves. It is smoked either in a pipe or a hand-rolled cigarette, called a "joint." Other common names for marijuana are pot, weed, grass, herb, and reefer.

Marijuana is fairly easy for young people to get. It also tends to be the first illegal drug they try. After smoking marijuana, teens may go on to try "harder" drugs, such as cocaine and LSD.

Signs your child may be using marijuana

Your child:

  • Has red eyes; uses eye drops a lot
  • Is hungry often and even gains weight
  • Is less motivated and has an "I don't care" attitude
  • Withdraws from the family; spends more time in his or her room or away from home
  • Forgets things; has trouble paying attention or communicating
  • Buys things like CDs and T-shirts with pro-marijuana messages or symbols
  • Starts missing school or shows a drop in school grades
  • Has new friends and interests; gives up old hobbies, sports, or other activities

Some short-term effects of smoking marijuana include:

  • Calm, relaxed, sleepy feeling
  • Increased appetite
  • Dry, bloodshot eyes; dry throat and mouth
  • Increased heart rate
  • Slowed reaction time
  • Poor short-term memory
  • Anxiety, panic attacks, or paranoia

Why young people try marijuana

There are many reasons why young people use drugs. Some of the most common reasons are:

  • To fit in with their friends
  • To avoid dealing with strong emotions or problems
  • Because they are curious
  • To rebel and be different
  • For a quick way to feel good and have fun
  • Because some media show drug use as "cool" or normal and not having any bad effects

Some teens may think using marijuana will make them "cool" or seem more adult-like. They need to know that marijuana use is not a normal step in growing up, despite what their peers may say.

The risks

Over time, marijuana may cause serious physical effects in teens who are still growing and maturing. These include:

  • Lower sperm count and testosterone levels in males (Testosterone is a hormone that controls hair and penis growth, muscle mass, and voice changes during puberty.)
  • Irregular menstrual periods and ovulation in females, which can lead to infertility
  • Heart and lung damage
  • Cancer
  • Memory problems
  • Psychological dependence on the drug

Marijuana can make it difficult for a person to think, listen, speak, remember things, solve problems, and form concepts. It can also affect how well your teen does in school. Heavy, chronic marijuana smokers often have less drive and ambition.

The effects of marijuana can make driving or playing sports risky. This is because marijuana impairs complex motor skills and the ability to judge speed and time. Using drugs like marijuana increases the risk of injury, such as from vehicle crashes.

In adolescence, sexual feelings are evolving and changing. Smoking marijuana can confuse these feelings and cause your teen to take sexual chances. This could lead to an unplanned pregnancy or a sexually transmitted disease (including HIV, the virus that causes AIDS).

Remember

If your teen is using marijuana, he or she needs your help. Pediatricians, family members, teachers, youth groups, mental health professionals, and clergy can provide support for your teen to stop smoking marijuana. If the problem is too much for you to handle on your own, get professional help. Your teen may need counseling, a support group, and/or a treatment program.
