This document presents information about marijuana including what it is, how people use it, and its effects on the brain and health. It discusses that marijuana is a preparation from the cannabis plant that is commonly used as a psychoactive drug. It can be smoked in joints or pipes, or consumed in foods. When used, THC passes to the brain where it overactivates receptors and causes short-term effects like altered senses and mood before leaving the body. Long-term use may negatively impact brain development and increase risks of mental health issues like depression. Other health risks include breathing issues and increased heart rate. Treatment options for marijuana addiction include behavioral therapies and counseling since no medications currently exist.

5. I- what is Marijuana?
Marijuana , also known
as Cannabis and by numerous
other names . Is a preparation of
the Cannabis plant intended for
use as a psychoactive
drug or medicine.
Marijuana is the most commonly
used drug in the United States.

7. Ii-How do people use marijuana?
• People smoke marijuana in hand-
rolled cigarettes (joints) or in pipes
or water pipes (bongs). They also
smoke it in blunts which is emptied
cigars that have been partly or
completely refilled with marijuana .
To avoid inhaling smoke, more
people are using vaporizers.

8. These devices pull the active
ingredients (including THC) from
the marijuana and collect their
vapor in a storage unit. A person
then inhales the vapor, not the
smoke. Users can mix marijuana in
food , such as brownies, cookies, or
candy, or brew it as a tea. A newly
popular method of use is smoking
or eating .

13. Iii-How does marijuana affect the brain?
1-Short-term effects :
When a person smokes marijuana, THC
quickly passes from the lungs into the
bloodstream. The blood carries the
chemical to the brain and other organs
throughout the body. The body
absorbs THC more slowly when the
person eats or drinks it. In that case,
the user generally feels the effects
after 30 minutes to 1 hour.

14. Marijuana overactivates parts of the
brain that contain the highest number
of these receptors. This causes the
"high" that users feel. Other effects
include:
-altered senses (for example, seeing brighter
colors)
-altered sense of time
-changes in mood
-difficulty with thinking and problem-solving
- ….

15. 2- Long-term effects
• Marijuana also affects brain
development. When marijuana users
begin using as teenagers, the drug may
reduce thinking, memory, and learning
functions and affect how the brain
builds connections between the areas
necessary for these functions.
Marijuana’s effects on these abilities
may last a long time or even be
permanent.

16. Cannabis use may increase the risk of
depression.

17. IV-What are the other health effects of marijuana?
• Breathing problems: Marijuana smoke irritates the
lungs, and frequent marijuana smokers can have
the same breathing problems that tobacco smokers
have.
Researchers still do not know whether marijuana
smokers have a higher risk for lung cancer.
• Increased heart rate: Marijuana raises heart rate for
up to 3 hours after smoking. This effect may
increase the chance of heart attack. Older people
and those with heart problems may be at higher
risk

18. V-How can people get treatment for marijuana
addiction?
• Long-term marijuana users trying to quit
report withdrawal symptoms that make
quitting difficult. These include:
• grouchiness
• sleeplessness
• decreased appetite
• anxiety
• cravings

19. • Behavioral support has been effective in
treating marijuana addiction. Examples
include therapy and motivational
incentives (providing rewards to
patients who remain substance free)
• No medications are currently available
to treat marijuana addiction. However,
continuing research may lead to new
medications that help blocking the
effects of marijuana, and preventing
relapse.
