There are thousands of Cannabis strains, each having their own characteristics, different effects and suitability to a different medical condition. The Cannabis strains are categorized according to the quantity of THC and CBD in them. It is important to select a strain that is appropriately suited in its composition to the situation you are trying to treat, when there are strains in which the CBD percentage is higher, they will act against anxiety, seizures, PTSD and more, whereas strains with higher levels of THC are more suitable for complaints of pain, loss of appetite and nausea. Strains with high levels of THC create a sense of “high”, whereas strains with high CBD levels are able to neutralize the sense of “high” caused by taking a high dosage of THC.
