cbd symptoms

Medical marijuana is frequently prescribed to people with intractable (treatment-resistant) pain, including those with terminal cancer. There is some evidence that CBD contributes to this benefit.

In all but a few studies, lower doses of CBD (10 milligrams per kilogram, mg/kg, or less) improved some symptoms of anxiety. Higher doses (100 mg/kg or more) exhibited virtually no effect.

Nerve Pain

According to the investigators, men provided 300 mg of CBD exhibited less anxiety than those given a placebo. Interestingly, those provided 100 mg or 600 mg of CBD oil did not.

CBD oil can interact with certain medications, including some drugs used to treat epilepsy. CBD inhibits an enzyme called cytochrome P450 (CYP450), which metabolizes certain drugs. By interfering with CYP450, CBD may either increase the toxicity or decrease the effectiveness of these drugs.

The findings suggest that CBD oil may be a suitable complementary therapy for people whose hypertension is complicated by stress and anxiety. However, there is no evidence that CBD oil can treat hypertension on its own or prevent hypertension in people at risk. While stress is known to complicate high blood pressure, it cannot cause hypertension.
