It’s not until you put cannabis under high heat that the process of decarboxylation breaks down that raw form into the psychoactive compounds that can actually benefit the body. This unlocking process […]
With our smartphones serving as the vital tether that links us to the rest of our lives, it’s no wonder how low batteries and power emergencies can occasionally feel like a life-and-death situation.
