Can Smoking Cause Depression?
You may have heard that marijuana has an effect on dopamine in the brain. Dopamine is a brain chemical that makes you feel rewarded. Many drugs stimulate this pathway, and marijuana is no exception. In the short term, marijuana can increase dopamine activity. However, after regular and long term use, marijuana can decrease levels of dopamine.
These effects are temporary, and users return to normal after quitting marijuana. Dopamine is a brain chemical associated with pleasure and reward.
Many biological functions involve dopamine, including appetite, attention, learning, sleep, sex, movement and mood. The dopaminergic dopamine-releasing system is also associated with addiction.
Most behaviours that are considered addictive activate the dopamine reward pathway, including drug use, food, gambling, and sex. Many drugs of abuse, including cocaine, opioids, alcohol, and marijuana can increase dopamine levels in the brain. Specifically, these drugs activate the area known as the reward pathway.
When dopamine is released in this area, you feel good. How Does Marijuana Affect Dopamine? The cannabinoids in marijuana do not act on dopamine neurons directly.
Instead, they act on the endocannabinoid system. Cannabinoid receptors are found in many brain areas that have dopamine neurons. However, dopamine neurons in the reward pathway are inhibited by GABA neurons which do have cannabinoid receptors. What happens when you inhibit an inhibitor?
The dopamine neurons become disinhibited, and more active. GABA is naturally inhibited by other cannabinoids produced by the brain. The action of natural cannabinoids, known as endocannabinoidsis believed to play an essential role in the release of dopamine in day-to-day functions.
The researchers concluded that the cannabinoid system may help facilitate dopamine release during exercise, and probably other reward-related functions as well. Shutterstock When marijuana is ingested, it increases dopamine in the reward pathway.
However, the link between marijuana and dopamine is not completely straightforward. Factors like tolerance, history of use, and strain content can all impact how marijuana affects dopamine. A animal study found that THC stimulated dopamine neurons in the midbrain of rats.
A study confirmed that marijuana increases the amount of dopamine in the midbrain reward pathway in humans, as well. The effect of THC on dopamine explains why marijuana makes you feel good. CBD, on the other hand, does not seem to impact dopamine.
In a studyresearchers found that CBD did not increase dopamine in reward pathways. In a reviewresearchers concluded that low doses of THC increase the conversion of a precursor into dopamine, while high doses result in a decrease.
Long-Term Effects Regular marijuana use may cause a reduction in dopamine, but these effects are temporary. A study found that long-term marijuana use reduced dopamine in the medial prefrontal cortex, an area of the brain associated with complex tasks like decision-making, memory, and planning.
Long-term reductions in dopamine are also thought to play a role in marijuana withdrawal symptoms. A study found that marijuana users who were abstinent for a period of time had normal levels of dopamine and receptors in the reward pathway of the brain.Six Things to Do Instead of Smoking If you're thinking of quitting, read below for the three steps you should take first.
