THC oil, marijuana oil, and cannabis oil are generally associated with the same product. Essentially, they all mean the same thing. With the help of alcohol, this oil is made by extracting the resin of the female marijuana plant. Remember, the marijuana plant is the high-THC strain. The resin dissolves in alcohol and then the alcohol evaporates. The residue will consist of a thick syrup abundant in THC. This type of oil is illegal because of the high levels of THC.
So is it possible that despite all this anecdotal evidence, low-dose CBD is a placebo? Sure, because, say it with me: We don’t know anything about CBD. “Unfortunately,” says Baron, “we are nowhere near close to having any definitive trials on effectiveness for most symptoms claimed to benefit from CBD with trials that are scientifically relevant, such as prospective randomized placebo-controlled trials.”
Scientifically, the difference between what we refer to as hemp and marijuana comes from the intention the strain was bred for. The main difference between hemp and marijuana is the level of THC in the plant. Hemp has high levels of cannabidiol (CBD) and very low levels of tetrahydrocannabinol (THC). Marijuana is recognized for having high levels of THC and lower in CBD. In order to be considered hemp, the plant must have less than 0.3 percent THC. High levels of THC are responsible for the intoxicating feeling that marijuana is known for.  
The term "CBD" is a nickname for cannabidiol, which is one of several cannabinoids, or chemical compounds, that are found in cannabis and hemp plants. Of course, the most famous cannabinoid is tetrahydrocannabinol, or THC, which is the main psychoactive component in marijuana (aka, the part that gets you high). Because CBD is not psychoactive, it does not create the same buzzy effects typically associated with marijuana when ingested.
One study found that placebos sometimes work even when the subject knows it’s a placebo. Another, using that same public speaking setup that CBD studies have used, found that anxiety treatments are particularly susceptible to the placebo effect, with 40 percent of placebo-treated patients showing a decrease in anxiety symptoms while tasked with speaking to a crowd.
One of the strongest nutraceutical CBD oils is called Charlotte’s Web, with a 50mg dose. Charlotte’s Web is produced in Colorado by the Stanley Brothers, and named after Charlotte Figi, a girl who became famous in the US after her frequent seizures, brought on by the rare Dravet syndrome, were greatly reduced when she started taking CBD oil aged five. The company makes THC products too and is extremely successful, having just offered shares on the Canadian securities exchange, raising about $100m.
