It is well known that cannabis plants obtained from uncontrolled sources may be contaminated with various harmful substances , sometimes leading to severe health issues or hospitalization . Contaminants include chemicals that were intentionally added in order to increase yield, weight, or potency (e.g., pesticides, metal particles , synthetic cannabinoids ) but also agents that entered the plant unintentionally (e.g., heavy metals, molds and bacteria , aflatoxins). For example, pesticides are frequently present in cannabis sold by Dutch coffee shops , but were also found in cannabis offered under state law in California  as well as medicinal cannabis from licensed producers in Canada . If any of these contaminants were present in hemp used for CBD extraction, they would likely end up in a concentrated form in the final oil. One contaminant specifically relevant to cannabis (CBD or THC) oils is the residual presence of toxic solvents used during the extraction procedure .
Let’s start by looking at THC. THC (tetrahydrocannabinol) is the compound found in cannabis with psychotropic properties. Medical marijuana companies breed their plants to have the highest concentrations of this compound. It is associated with the feeling of being high that marijuana smokers experience. Effects include feelings of euphoria, pain relief and sometimes increased anxiety and paranoia.
I used a “cbd tincture 250mg”. After about 3 weeks I started passing blood and protein in urine. I stopped and it cleared up. A couple weeks later I decided to try again and within 3 days it happened again. Could this be due to the type of oil I used or might I have the same problem with any oil I try? It was helping my hip pain and crohns. Thanks!
