For the most part, CBD products are safe to use for everyone. Too much CBD can have effects such as drowsiness, reduced appetite, fatigue, dry mouth and diarrhea. It may also affect certain medications such as blood thinners. Another concern is the irregularity of dosage and purity. Studies have shown that some CBD products that were purchased online had less CBD than the label suggested. Also found in those same products was THC. It is extremely important to purchase CBD products from a reputable company online that offers COA,s (Certificate of Authenticity) and has their products triple lab tested. There is a highly reputable, trustworthy website that tests the purity of CBD products from various companies called leafly.com. Check out how Patriot Supreme pure CBD oil rates according to Leafly. Bottom line, if you take medications, or are pregnant, it is always best to speak to your health care provider before taking any kind of supplement.
