Many drugs exit your system relatively quickly, meaning you may pass a drug test shortly after using them--perhaps in just a few days. Meth, however, is not one of those drugs. Commonly called ice, glass, or crystal, it remains detectable in the body long after the impact of the drug has worn off.
Even the instant effects can last for quite some time. Some have even said they may last for as long as 16 hours, though there are many factors that have to be considered, such as how much is taken, how frequent the drug use is, and the like.
The way that meth works is just like other amphetamines. It can tighten the user's blood vessels, stimulated the person's heart, stimulate his or her breathing, and cause dopamine levels in the brain to spike. Dopamine is a neurotransmitter, meaning it helps the brain pass signals regarding movement, emotion, pain and pleasure. All of these can be heightened when there is excess dopamine in the brain. These heightened levels then combine with the effects of the faster heart rate, breathing, and the rest.
As far as dopamine production is concerned, meth is one of the more potent drugs. Cocaine also increases dopamine levels, and experts have found that they can go up by 400 percent. While this is significant, studies have shown that crystal meth can increase the levels by as much as 1,500 percent.
Those who are accused of using drugs like meth or cocaine need to know what legal options they have in Ontario, and they should also consider what type of evidence is needed in court--such as the presence or lack of trace amounts of meth that can still be found long after initial use.
