What is Considered High THC?

Cannabis is one of the most widely consumed drugs globally, used as a medicine long before its legalization in the United States and Canada, among other countries. There are accounts that the Scythians, the Japanese, the Chinese, and the Persians used it for medicinal purposes before the discovery of cannabis components like THC and CBD. These people utilized marijuana in different ways without any idea of its potency.

Pharmacological experiments to measure cannabis potency only started in the late 1950s, years after marijuana is deemed illegal. The initial THC concentrations recovered were only 2%. Two decades later weed emerged, and the potency increased along with it containing 3% to 4% of THC. The expansion of the market can explain this rise. People started to experiment with different variants throughout the years. The competition is fierce in the cannabis industry, so people came up with new strains and more potent weed.

What is a High THC Strain?

If a certain strain of weed is strong, it’s likely a high-THC strain. The discovery of the psychoactive component that contributes to marijuana potency only came in 1960. The experiment of researchers with rhesus monkeys found that THC matched the cannabinoid receptors in our brain. They perceived the calming and sedating effects of the THC content in marijuana. There has been a dramatic rise in the THC content between 1995 and 2015, several years after its great discovery.

The increase can be associated with the expansion of cannabis in the industry as an aftermath of its legalization. Many variants are now available that suit your preference. You can consume marijuana of different strains in many ways like smoking, vaping, and eating. Cannabis became accessible to many increasing up to 65% of adolescent users. The problem arises with the increasing potency contributing to high probabilities of addiction. This issue alarmed the public resulting in investigations with the rise of marijuana potency throughout the years. Marijuana advocates debate that THC is not the sole identifying factor to determine the strength of the high. Instead, different factors affect the increase in potency. These factors include:

  • Plant genetics: Female varieties of marijuana are more potent than males.
  • Methods of harvest and processing: The time of harvest indicates the level of potency.
  • The desire of growers to maximize profit: They modify marijuana cultivation to optimize yield and harvest the most potent product possible.
  • Growing Climate and Conditions: Studies show that climate change contributes to increasing marijuana potency. The higher carbon levels help marijuana survive drought and increase its strength.

The potency of marijuana is also dependent on the complexity of the plant. Marijuana narrows down into two distinct species, Indica and Sativa. Strains comprised of a mix of these two species are referred to as hybrids. These three groups have different effects depending on the levels of THC and CBD they possess. Cannabinoids such as THC have significant effects, but it also depends on how all the compounds interact with our brain. On average, 18% of THC concentration is enough to make someone high.

Use Precaution when Using High-THC Strains of Cannabis

Also, allow yourself plenty of time to recover, as the effects of marijuana can restrict you from driving or performing well at work. You should let at least 6 hours pass before you do anything strenuous after taking cannabis. Another suggestion is you can also neutralize the negative effects of THC through CBD strains. Combine the two with a ratio of 1:1, 2:1, or 5:1 depending on your preference. It is to minimize the harmful effects associated with the psychoactive substance of marijuana, THC.
