Today's marijuana is far more potent than those used by pot lovers in the 70s and 80s. According to CBS News, researchers from Charas Scientific have noticed a 20 to 30% increase in THC or Tetrahydrocannabinol the chemical that give marijuana users the feeling of being high.
Charas Scientific is one of the laboratories certified by Colorado to conduct tests on the potency of marijuana. The findings were presented at a meeting of the American Chemical Society (ACS). The state has legalized the recreational use of marijuana last year.

The THC increase in marijuana is a source of concern among health officials. Researchers also fear adverse reactions for new users while frequent users face higher chances of addiction.
Officials and scientists are not yet certain on the reasons behind the rise of THC levels although cross-breeding practices among marijuana growers could have altered the chemical make up of the new varieties.
Low CBD And Microbes Discovered
Charas Scientific researchers also discovered lower or no Cannabidiol (CBD) in the samples they've examined which may be a result of cross-breeding. CBD is a chemical compound in marijuana that may have medicinal applications, from Alzheimer's disease and schizophrenia.
Lab findings also show the presence of microbes in the samples submitted by marijuana growers. Health officials are now drafting standards for organic contaminants after another Colorado lab detected E. Coli, Salmonella and other harmful microorganisms in the samples.
