Cannabis

Conclusion

Cannabis has several different effects on your brain. These are generated by its active agent THC.

THC mimics the neurotransmitter anandamide, and it also indirectly increases the release of dopamine. That gives you a pleasant feeling. The risk of addiction to cannabis is lower than that of drugs like cocaine or speed.

THC also binds at other points in your brain. That can adversely affect your short-term memory and your coordination. Destruction of brain cells has not been proven in the case of cannabis.
