I smoke weed since last two yrs. What are possible damages my health may go through?

Question

Brain imaging scans of heavy marijuana smokers have revealed changes in blood flow to parts of the brain involved in memory and attention. Researchers have also noted differences in the size and shape of the thalamus, the part of the brain that's involved in consciousness and information processing.
Heavy pot smokers in studies score lower than non-users on tests of memory, attention, and learning. The more they smoked, the worse they did.
The effects of smoking pot may be even more pronounced in teenage smokers than adults, because teens' brains are still developing.
Regular users are more likely to be diagnosed with schizophrenia, especially when they have a family history of the condition.
Other Health Effects
Marijuana can have effects beyond the lungs and brain. These include:

Anxiety
Depression
Fast heart rate
Increased risk of heart attack (within the first hour after smoking)
Suicidal thoughts in teens
It is Addictive.
People who stop smoking pot don't have the same withdrawal symptoms -- like anxiety and sweating -- they'd get if they were addicted to a drug like heroin. Yet those who use marijuana all the time can have a hard time stopping.
