Canada became the second country in the world after Uruguay to legalize the possession and consumption of recreational marijuana. The cannabis market opened nationwide on Wednesday (17/10) at midnight, although many still question the health, legal, and public safety implications of marijuana use. A public awareness campaign and information about the new law was sent by the government to 15 million households in Canada. Just like other drugs, based on natreleaf.com, marijuana used in the medical world can also cause various side effects such as red eyes, depression, dizziness, increased heart rate, hallucinations, low blood pressure. Besides, this drug can also affect body movement and coordination. The National Institute on Drug Abuse states that marijuana can make you addicted and increase your desire to use other drugs.
Marcel Bonn-Miller, Ph.D., a substance abuse specialist at the School of Medicine, University of Pennsylvania, Perelman School of Medicine, states that the more frequent and higher THC levels are used, the more likely you are to experience addiction. Therefore, doctors will be very careful when they have to give this one drug so that the body does not have a severe addictive effect. Besides having benefits in the medical world, weed (another name for marijuana) can also cause health problems that are not kidding. This especially happens when you use it carelessly without the doctor’s permission.
The active ingredient in marijuana, delta-9 tetrahydrocannabinol or THC, acts on the cannabinoid receptors on nerve cells and influences the activity of these cells. What you should know is that some areas of the brain have a lot of cannabinoid receptors, but other areas of the brain have few or none. When you take it in high doses, users will experience various symptoms such as hallucinations, delusions, memory impairment, and disorientation (dazed). This happens because the cannabinoid receptors are overactive. Marijuana can cause your heart rate to increase by 20-50 times more per minute. The effects can be more severe when you use them together with other medicines. When your blood pressure and heart rate jump sharply, you are four times more likely to have a heart attack in the first hour after smoking marijuana.
