Pharmacological effects of marijuana
The term marijuana is used colloquially as a description of all properties found in the plant. Researchers have discovered over 100 different chemicals from the plant. They collectively call them cannabinoids and are mainly extracted from Cannabis Sativa. The largest quantities of cannabinoids so far discovered are THC and CBD.
Both cannabinoids contain receptors CB1 and CB2 embedded in G proteins. Their use led to the suppressed production of cAMP. They also activate potassium and hyperpolarize neurons. When THC is inhaled or ingested, it increases plasma concentration which increases relaxation and sensory experiences. It may increase heart rate or blood pressure. Long-term use may cause serious effects on:
- Immune system
CBD is known to cause:
- Muscle relaxation
- Improved mood
- Blood pressure normalization
- Appetite stimulation
- Apoptosis in cancer cells
There is a wide difference in cannabis plants grown around the world. They contain different quantities of THC and CBD, some of which are not commercially viable. Processors can extract until they get enough quantity acceptable for pharmacological use.
Cannabis Sativa contains the highest concentration of THC and CBD. It is available as a prescription drug, although many users may prefer to buy it without a prescription. It is quickly absorbed into the body and delivered to the brain. It can reach peak concentration within 22 minutes.
Cannabis is useful to the body in many ways. Generally, cannabinoids are highly lipophilic. Due to this, they are often stored in the muscles, liver, spleen, and bloodstream. When it stays for a longer time in the body, it could lead to mental, physical, and toxic problems that are difficult to correct. It helps treat many types of diseases, but if not well managed, it can also lead to nausea, anxiety, insomnia, depression, irritation, and nightmares.
