When you first start taking medical cannabis, you’ll begin with a low dose of THC or CBD and it’s unlikely that you’ll get high. The doctor looking after you and providing your medical cannabis prescription can discuss this further with you.
Medical cannabis can cause a high if you take a high dose of THC. THC is the active substance in medical cannabis that can cause a high and is known as tetrahydrocannabinol. CBD stands for cannabidiol and doesn’t cause a high.
