There are no studies in people of the effects of marijuana oil or hemp oil.

Some people have trouble with increased heart rate, decreased blood pressure (especially when standing up), dizziness or lightheadedness, and fainting. These drugs can cause drowsiness as well as mood changes or a feeling of being “high” that some people find uncomfortable. They can also worsen depression, mania, or other mental illness. Some patients taking nabilone in studies reported hallucinations. The drugs may increase some effects of sedatives, sleeping pills, or alcohol, such as sleepiness and poor coordination. Patients have also reported problems with dry mouth and trouble with recent memory.

Possible harms of marijuana

The effects of marijuana also vary depending on how marijuana compounds enter the body. The most common ways to use marijuana are in food (edible marijuana) and by smoking or vaping it (inhaled marijuana):

There have been some early clinical trials of cannabinoids in treating cancer in humans and more studies are planned. While the studies so far have shown that cannabinoids can be safe in treating cancer, they do not show that they help control or cure the disease.

There are 2 chemically pure drugs based on marijuana compounds that have been approved in the US for medical use.

Conclusion: This review also illustrates that some important toxicological parameters are yet to be studied, for example, if CBD has an effect on hormones. Additionally, more clinical trials with a greater number of participants and longer chronic CBD administration are still lacking.

Fifteen male, healthy subjects with minimal prior Δ9-THC exposure (<15 times) were tested for CBD affecting Δ9-THC propsychotic effects using functional magnetic resonance imaging (fMRI) and various questionnaires on three occasions, at 1-month intervals, following administration of 10 mg delta-9-Δ9-THC, 600 mg CBD, or placebo. Order of drug administration was pseudorandomized across subjects, so that an equal number of subjects received any of the drugs during the first, second, or third session in a double-blind, repeated-measures, within-subject design. 54 No CBD effect on psychotic symptoms as measured with PANSS positive symptoms subscale, anxiety as indexed by the State Trait Anxiety Inventory (STAI) state, and Visual Analogue Mood Scale (VAMS) tranquilization or calming subscale, compared to the placebo group, was observed. The same is true for a verbal learning task (=behavioral performance of the verbal memory).

Introduction

Over the course of 1 week, participants used the inhaler when they felt the urge to smoke and received a dose of 400 μg CBD via the inhaler (leading to >65% bioavailability); this significantly reduced the number of cigarettes smoked by ca. 40%, while craving was not significantly different in the groups post-test. At day 7, the anxiety levels for placebo and CBD group did not differ. CBD did not increase depression (in contrast to the selective CB1 antagonist rimonabant). CBD might weaken the attentional bias to smoking cues or could have disrupted reconsolidation, thereby destabilizing drug-related memories. 59

Fifteen neuroleptic-free patients with Huntington’s disease were treated with either placebo or oral CBD (10 mg/kg b.w. per day) for 6 weeks in a double-blind, randomized, crossover study design. Using various safety outcome variables, clinical tests, and the cannabis side effect inventory, it was shown that there were no differences between the placebo group and the CBD group in the observed side effects. 6

Moreover, the elevated IL-1 beta and TNF alpha levels observed in the transgenic mice could be reduced to WT (wild-type) levels with CBD treatment. Using statistical analysis by analysis of variance, this was shown to be only a trend. This might have been caused by the high variation in the transgenic mouse group, though. Also, CBD increased cholesterol levels in WT mice but not in CBD-treated transgenic mice. This was probably due to already elevated cholesterol in the transgenic mice. The study observed no side effects. 31 and references within
