There's some confusion about the use of the name "Quebec Gold." Technically it refers only to this strain, but it's often used to describe a wide range of similarly potent strains out of Quebec.
This one, the real thing, is a sativa-dominant hybrid with an unknown ratio of sativa to indica. The strong, psychoactive high follows those sativa leanings, with calming yet focused effects that include an intense dose of euphoria, mental clarity, and a boost of happiness. It also delivers a powerful case of the munchies, ideal for treating eating and wasting disorders.
Quebec Gold can be a good choice for medicating anxiety, depression, eye pressure, headaches, and everyday stress. THC is abundant in this strain, topping at least 18% in available tests. But CBD levels are far lower, far too low to recommend this strain as a good medicine for seizures or other conditions that respond to that substance. Quebec Gold produces a smell of citrus and lemon, while the flavor also includes notes of pine.
As far as side effects go, dry mouth and red eyes are widely reported. This strain used to be very popular, but its time has largely passed; these days it's hard to find anywhere outside Canada.
