What are THC & CBD?
THC – Tetrahydrocannabinol. THC, is the main psychoactive substance found in the Cannabis plant. Tetrahydrocannabinol, usually refers to the naturally existing isomer of delta-9-THC.
THC has an extremely low toxicity and the amount that can enter the body through the consumption of cannabis plants poses no threat of death. It is generally considered impossible to overdose on marijuana, as the user would certainly either fall asleep or otherwise become incapacitated from the effects of the drug before being able to consume enough THC to be fatally toxic. In lab animal tests, scientists have had much difficulty administering a dosage of THC that is high enough to be lethal.
Incidental observations have also revealed therapeutically useful effects. This occurred in a study with patients with Alzheimer’s disease wherein the primary issue was an examination of the appetite-stimulating effects of THC. Not only appetite and body weight increased, but disturbed behaviour among the patients also decreased. Some recent investigations have also shown that THC in low doses improves the efficacy of other antiemetic (appetite enhancing) drugs if given together.
In some MS patients, benefits of reduction of tremor have been observed following the administration of THC. In patients with Epilepsy the anticonvulsant activity of phenytoin and diazepam have been potentiated by THC. Some epileptic patients continue to utililize cannabis to control an otherwise unmanageable seizure disorder.
CBD - Cannabidiol. High CBD cannabis provides medical benefit without psychoactive effect. CBD is a cannabinoid with medical potential that is bred from cannabis when the goal is high THC content. Because CBD is not psychoactive, people who dislike the effects of currently available marijuana, or who are seeking medical benefit without feeling stoned, might like high-CBD strains bred low in THC.
High CBD strains may enable patients that need large doses of cannabinoids to ingest the dose they need and still remain functional. CBD boosts the pain-killing effects of THC while moderating its psychoactivity.
CBD has anti-inflammatory, anti-oxidant, anti-convulsant, anti-anxiety and neuroprotective properties, according to a rapidly expanding array of published studies. Recent studies have also shown cannabidiol to be as effective as atypical antipsychotics in treating schizophrenia.
CBD also has a direct inhibitory effect on certain cancer cells. In November 2007 it was reported that CBD reduces growth of aggressive human breast cancer cells in vitro and reduces their invasiveness. It thus represents the first non-toxic exogenous agent that can lead to down-regulation of tumor aggressiveness.
