Like many other drugs, marijuana contains substances that resemble our natural neurotransmitters. In this case, it is tetrahydrocannabinol or THC, which has the same effect on our brain as anandamide: short-term, feeling of well-being and amplification of pleasurable sensations, elevation of the pain threshold, and also some interference with the formation of memories and with motor functions.
But marijuana also contains another substance called cannabidiol or CBD, which when reaches the brain increases the levels of another endogenous neurotransmitter called 2-AG, which deals with the regulation of appetite (hence the intake results in intense hunger), and much more important, the immune system and the regulation of pain. THC is psychotropic, and it is the part of cannabis that gives you the “recreational” effects. CBD does not produce these effects, but it does affect the functions of the brain and health in general, in many cases in a beneficial way.
Relieve Anxiety, Or Not
The use of marijuana in moderation induces feelings of relaxation, but from a certain dose, instead of reducing anxiety, it causes anxiety. It is the sad experience of someone who has eaten that cannabis cake and has felt great at first, but as the digestion continued and THC blood levels increased, they found themselves living a nightmare of nerves and cramps.
It can slow the development of cancer and alleviate the effects of chemotherapy
When used in the medical circles, it is called medicinal marijuana. The same CBD component can slow the development of breast cancer according to the study of the University of San Francisco. Other studies with mice have shown that THC also slows the growth of tumours, and another more recent, combining CBD and THC, found that adding to the radiation therapy was a more effective treatment for the development of glioma, the most common brain tumour. However, these results have not yet been replicated in humans.
Cancer patients treated with chemotherapy suffer from nausea, vomiting and loss of appetite. Several studies have found that smoking marijuana or using THC-based drugs can relieve these symptoms.
However, this does not mean that any patient can start using it. Only a doctor can deliver these medications. It is not the same type of marijuana that people smoke usually. Scientists are studying the ways in which marijuana may be useful for other disorders, but the research will take years.
Symptoms of Marijuana Abuse
If this drug is consumed frequently it can bring significant risks to health, this can include memory problems, decreased learning and cause different behaviours strange to the person. For example, some behavioural symptoms may be: laughing out loud without knowing why, demotivation, family conflicts, criminal behaviour, reduction of inhibition and work irresponsibility.
Depending on the use that is given to cannabis, this substance can be beneficial, but, on the contrary, if it is abused, it can be an injustice. The marijuana results in effects on the body, which, depending on its use, can be both positive and negative.
To define if the use of marijuana has become an abuse, we must study many factors related to its use such as the social, economic context, the route of administration or lifestyle, among others.
