Short-term effects
Physical effects of short-term (acute) marijuana use can include:
red eyes,
increased heart rate,
drop in blood pressure,
light-headedness (fainting),
heart attack, and
stroke.
Long-term effects
The physical health effects of marijuana use mainly involve your lungs and heart.
Lung and breathing problems
Like tobacco smoke, marijuana smoke is a mix of toxic substances. Marijuana smoke irritates the throat and lungs, causes coughing, and is associated with symptoms of bronchitis. Marijuana smoke also contains many of the same cancer-causing materials as tobacco smoke.
Regular marijuana smokers may suffer the same symptoms as tobacco smokers, such as:
chronic (ongoing) cough,
increased phlegm buildup in the throat (mucus),
frequent chest problems, and
greater risk of lung infections.
Heart problems
The heart normally beats about 70 to 80 times a minute, but using marijuana can double that rate. This increased rate can put a lot of stress on the heart. Smoking marijuana can also cause an increased risk of stroke. The risks of heart attack or stroke from marijuana use appear to increase with age and with pre-existing heart or blood circulation problems.
Pregnancy problems
Women who are pregnant may be particularly at risk for health problems related to marijuana use.
Marijuana smoking during pregnancy has been associated with long-lasting harm to the exposed child's memory and other brain functions as well as hyperactive behaviour. Like alcohol, the toxins in marijuana are carried in the mother's blood to her unborn child. Marijuana use mainly affects the development of the fetus' nerves and brain.
The toxins in marijuana are also carried in breast milk and can be passed to her growing baby.
Studies show that some babies born to women who used marijuana during pregnancy tend to have:
delayed visual responses,
shaking,
a high-pitched cry, and
decreased birth weight.
In older children, problems are often seen while they are at school. Exposure to marijuana may affect their:
memory,
problem-solving skills,
emotional and behavioural responses, and
ability to maintain focus and pay attention.
Did you know?
Studies show that the average level of THC, the principal "mind-altering" component of marijuana, has increased by 300% to 400% over the last few decades. Learn more about marijuana.更多精彩文章及讨论，请光临枫下论坛 rolia.net
