THC – Tetrahydrocannabinol or delta-9-THC is the active ingredient in marijuana that actually creates a euphoric effect in your brain and enters your body’s bloodstream quickly after you smoke it.

If cannabis is ingested, rather than smoked, it takes a longer time to be absorbed into the blood, usually from 30-50 minutes.

However, THC can be detected in the blood only for a short time, usually for a few hours. This is because delta-9-THC is quickly metabolized into molecules known as metabolites.

You might not know that at least 80 different metabolites are formed after smoking pot. These THC metabolites formed in your body are hydrophobic in nature and polar molecules of water can’t stick to it and dissolve them.

These metabolites rather associate themselves with other non-polar compounds, such as oils, body fat, and alkanes.

  • NEVER GIVE THE FIRST PEE OF THE DAY: This is usually referred to as “the first void.” Each time you urinate, the amount of THC metabolites will reduce to some extent. You should also avoid collecting the beginning of your urine stream because it will have the maximum amount of metabolites in it.
  • FLUSHING WEED OUT OF BODY BY DRINKING WATER– You need to drink large amounts of liquids so that the THC metabolites can be washed away faster. Remember not to drink alcoholic beverages! Never drink too much water at once because it can be dangerous.

Drinking too much water at once can cause water intoxication or water poisoning and can make you very sick.

NCI Admits That Cannabis Helps In Killing Cancer (UPDATED)

Cannabis Helps In Killing Cancer
NCI admits that Marijuana can help in killing cancer cells.

According to preclinical studies of cannabinoids by NCI, compounds found in cannabis have an unprecedented ability to kill brain tumors. The best thing about this new tumor killer – It doesn’t have any negative side effects.

Findings of the studies by NCI:

  • Studies in rats and mice have shown that CBD (Cannabinoids) may inhibit the growth of tumor by blocking cell growth, blocking the growth of blood vessels needed by tumors to develop and by causing cell death. Studies by NCI have shown that CBD helps in killing cancer cells without damaging normal cells.
  • Cannabinoids or CBD may help in protecting against inflammation of the colon. The studies show that it reduces the risk of colon cancer and may have potential in treating it.
  • NCI studies have shown that delta -9-THC in hepatocellular carcinoma cells damaged the cancer cells. Delta-9-THC causes these effects by acting on molecules that may also be found in non-small breast cancer cells and lung cancer cells.
  • According to a laboratory study of cannabidiol (CBD) in human glioma cells, chemotherapy such as temozolomide along with CBD and delta-9-THC makes chemotherapy more effective. The study found that CBD helps in increasing cancer cell death without damaging normal cells.
  • NCI laboratory studies have shown that CBD in estrogen receptor positive and estrogen receptor negative breast cancer cells cause cancer cell death, but it has little effect on normal breast cells.

Although these studies have shown that marijuana can kill cancer cells, yet it has not been legalized.
