CBD compared to Cannabis (Marijuana)
Please read our Cannabis Health and Safety page.
CBD: There is a consensus that CBD (cannabidiol) “has a good safety profile.” Consumers typically purchase CBD made from hemp, which contains no more than 0.3% tetrahydrocannabinol (THC).
Cannabis: There are numerous contraindications to be aware of for cannabis (marijuana) because of its THC content. Cannabis can interact with other medications, especially blood thinners. Federal agencies advise against using cannabis while pregnant or nursing. Check your state guidelines and talk to a medical professional before using these products. People with brain injuries may be more vulnerable to substance abuse, including abuse of marijuana.

Use different CBD/THC ratios throughout the day, for example, 20/1 ratio for daytime and 2/1 before bed, as THC may help with sleep.
Purity and accurate labeling: In these states where marijuana is legal (recreationally or medically), the products are tested for purity to some degree. However, the labeling for purity can be uneven – be sure to do your research. Every state is different, so be sure to ask about testing for heavy metals, molds, bacteria, yeast, pesticides, and potency. Labels may have some of this testing information. The label may also have a certificate of analysis from a lab or ask the dispensary for the certificate. Labels will also show which chemicals are used for extraction (you can select the safe ones) and whether the plant was grown without pesticides.
