<\/div>\n

Since smoking a joint can lead to a relaxing high, you might wonder about cannabis use and its effect on blood pressure. We know that <\/span>weed can make your eyes red<\/span><\/a>, but does it also raise or lower blood pressure, or does it not have any effect at all? If you have high blood pressure, is marijuana safe to consume?<\/span><\/p>\n\n\n\n

Here we'll address how smoking weed, including medical marijuana, could factor into your blood pressure levels.<\/span><\/p>\n\n\n\n

\n\tDoes marijuana lower or raise blood pressure?<\/h2>\n\n\n\n

To answer this question, we should focus on two of the <\/span>primary cannabinoids present in cannabis<\/span><\/a>: cannabidiol (CBD) and tetrahydrocannabinol (THC). Both may exert an influence on blood pressure levels.<\/span><\/p>\n\n\n\n

Dr. Bonni Goldstein, a medical adviser to Weedmaps and the director of Canna-Centers in Lawndale, California, outlined the potential effects of THC on blood pressure: <\/span><\/p>\n\n\n\n

\u201cTHC can affect blood pressure depending on the dose, the route of administration, a person's experience with THC, and a person's underlying health. Healthy volunteers that took THC had an increase in heart rate and decrease in blood pressure. In studies where people used THC while lying down, they had elevated blood pressure. When they stood up, their blood pressure dropped and they experienced low blood pressure.\u201d<\/span><\/p>\n\n\n\n

These sudden drops in blood pressure, also known as white outs or green outs, may indeed be linked to cannabis use. Dr. Melanie Bone, a board-certified OB-GYN and cannabis specialist who practices in West Palm Beach, Florida, told Weedmaps that \"cannabis may cause a drop in blood pressure on standing \u2014 known as postural hypotension.\" This type of drop in blood pressure is not desirable, as it can cause vertigo and even fainting. So, when we talk about \"lowering blood pressure,\" we do not necessarily consider that effect beneficial to health.<\/span><\/p>\n\n\n\t\t\t

Both THC and CBD may lower blood pressure in different ways. However, neither CBD nor THC should be considered a medical treatment for high blood pressure. <\/figcaption><\/figure>\t\t\t
