Keep in mind that cannabis affects everyone differently depending on their tolerance, weight, metabolism, and the strain itself.

The benefits of the highest THC strains depend on the specific effects of the cultivar itself, but strains high in THC are commonly used by medical cannabis patients seeking powerful relief from various conditions and recreational consumers who prefer a potent high. High-THC strains are said to be beneficial for pain relief, nausea and vomiting associated with chemotherapy and cancer, muscle spasms, and chronic conditions like multiple sclerosis, cancer, Parkinson’s disease, and more.   

The highest THC strains are best for medical patients and experienced cannabis consumers with a high THC tolerance. These stronger strains can adversely affect those new to cannabis or users sensitive to THC. If you’re new to potent weed, it’s recommended to start low and go slow, meaning starting with the lowest dose possible, waiting to see how it makes you feel, then slowly increasing your dose until you experience the effects you desire. Taking this approach can help you avoid becoming paranoid or anxious.
