Cannabis has a long history of use that dates back thousands of years. The first recorded use of cannabis has been traced to China, where it was used for food, textiles, and medicine. Hemp was eventually introduced to Europe, and later to the Americas, where it came to use for both recreational and ritual purposes.
While it can cause pleasant effects, TCH can also lead to adverse reactions as well. People can experience anxiety, memory problems, hallucinations, or delusions in some cases.

With the popularity of CBD, there has been a major market shift toward producing a seemingly endless variety of CBD products. Some of these products may contain traces of THC (around 0.3% to 0.9%), depending on how they’re formulated.
In 1970, the Controlled Substances Act classified marijuana as a Schedule I drug, identifying it as having a high potential for abuse and making the drug illegal at the federal level.
We’re definitely not dealing with the same pot as we were in the past. This is because today’s marijuana is much more potent, with THC levels averaging 9.6%, according to the National Institute on Drug Abuse (NIDA). By comparison, in the early 1990s, marijuana generally had a THC level of about 4%.
A 1991 study published in Pharmacology Biochemistry & Behavior examined the concentration of CBD in the blood after high doses daily. Over a six-week period, the research team administered a daily dose of 700 milligrams of CBD to 14 Huntington’s disease patients. One week after the dosing ceased, the CBD remaining in the blood was just 1.5 nanograms per milliliter and was “virtually undetectable” thereafter.
A 2018 review of existing CBD studies found that the estimated half-life of CBD was two to five days for those who took a daily oral dose. Other delivery methods delivered varied half-lives.
Bottom line: Consuming CBD products sublingually leads to higher bioavailability compared to consuming CBD products orally. Depending on the dose and your response to CBD, the effects from sublingual consumption should kick in within 30 minutes and last for one to three hours.
Oral ingestion is the most common method of CBD consumption. Administering a couple of drops of CBD oil directly into the mouth is certainly a convenient way to reap the potential benefits of this therapeutic cannabinoid. However, ingestion is not necessarily the most effective consumption method for those who want to feel the effects of CBD immediately.
Swallowing CBD oil prevents the cannabinoid from entering the bloodstream right away. Instead, it will travel first through the digestive tract and eventually on to the liver, where it will be broken down before finally reaching the bloodstream.
