Marijuana has an interesting effect on anxiety.  Some reports speak of paranoia after using marijuana, while others report a reduction in anxiety. Now, scientists have discovered evidence that may explain the complicated relationship between marijuana and feeling anxious.  When growing marijuana, a grow facility security plan is necessary for protecting cannabis growers from outside threats

The results are the first to confirm that cannabinoid receptors that are actually present in the part of the brain that regulates anxiety and fear: the amygdala. Cannabinoid receptors are chemically activated products of marijuana, called cannabinoids have been identified and many other brain regions, and the research by scientists were the first to suggest that marijuana may increase based on fear to act on the amygdala pathways in learning.

In 2011, a team found that when THC intensified in these rats reacted to certain smells that were trained to fear. But so far, no group had succeeded in characterizing cannabinoid pathways to the amygdala in such detail.

“We know where the receivers are, know their role, we know how these neurons make their own cannabinoids, ” said study author in a statement from the university.

“We can now see how the system is affected by stress … and for chronic use (marijuana)? It could fundamentally change our understanding of cellular communication in the amygdala.”

The new study links marijuana directly to the area of the brain that regulates the fight or flight response. This response or reaction is part of the overall process of the body to the threat factors or stress.

But why do some people feel more anxious after using marijuana and other less? it is not yet clear. The researchers used imaging techniques labeled antibody activity cannabinoids own body, instead of the derivatives of the plant. Humans and many animals naturally produce a series of similar to marijuana called endocannabinoids chemicals.

The study, which was conducted in mice also showed for the first time that endocannabinoids are produced by nerve cells in the amygdala. The team identified two separate mechanisms that might explain the opposite effects of marijuana on anxiety. Interestingly, endocannabinoids appear to act primarily on responses to reduce anxiety and fear.

The researchers conclude that further studies to explain why marijuana use sometimes results in an increase in paranoia are needed. At the same time, the author said that “the discovery could help explain why marijuana users say they take drugs, mainly to reduce anxiety.”

In fact, marijuana has gained considerable interest as a possible treatment for post-traumatic stress disorder (PTSD), a severe type of anxiety disorder.

The team of doctors also noted that regular use of marijuana may desensitize the brain cannabinoid receptors over time. Perhaps this could explain why novice users of marijuana are more likely to experienced users paranoid side effects. But ultimately, more research for more security is needed.
