Safety
The U.S. Food and Drug Administration does not strictly regulate herbs and supplements. There is no guarantee of strength, purity or safety of products, and effects may vary. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy. Consult a healthcare provider immediately if you experience side effects.
Allergies
Avoid with known allergy or hypersensitivity to cannabis, cannabinoids, or plants of the Cannabaceae family. Symptoms similar to hay fever and asthma have been reported.
Side Effects and Warnings
Cannabis may lower blood sugar levels. Caution is advised in patients with diabetes or hypoglycemia, and in those taking drugs, herbs, or supplements that affect blood sugar. Blood glucose levels may need to be monitored by a qualified healthcare professional, including a pharmacist, and medication adjustments may be necessary.
Cannabis may increase the risk of bleeding. Caution is advised in patients with bleeding disorders or those taking drugs that may increase the risk of bleeding. Dosing adjustments may be necessary.
Cannabis may cause low blood pressure. Caution is advised in patients taking herbs or supplements that lower blood pressure.
Drowsiness or sedation may occur. Use caution if driving or operating heavy machinery, if taking sedatives, barbiturates, or central nervous system depressants, or if consuming alcohol.
Cannabis may interfere with the way the body processes certain drugs, herbs, or supplements using the liver's cytochrome P450 enzyme system. As a result, the levels of these agents may change in the blood and may cause increased or decreased effects or potentially serious adverse reactions. Patients taking any medications should check the package insert and speak with a qualified healthcare professional, including a pharmacist, about possible interactions.
Use with caution in foods or supplements containing cannabis seeds or oil.
Use with caution in patients with liver disease, glaucoma, immune disorders, or a history of drug abuse or addictive behavior, or in patients taking agents for any of these conditions.
Use with caution in patients taking estrogen therapy, agents that may damage the liver, antipyrine, or p-glycoprotein-regulated drugs.
Avoid in individuals with asthma or byssinosis (lung disease).
Avoid inhalation or intravenous injection of cannabis.
Avoid use of cannabis products obtained illegally.
Avoid in patients who are pregnant or breastfeeding.
Avoid in patients with a known allergy or hypersensitivity to cannabis, cannabinoids, or plants of the Cannabaceae family.
