A strain for the advanced cannabis consumer, the general rule with Ghost Train Haze is to take it easy; with the right dosing however, consumers will find a pleasant, euphoric high that’s fit for accomplishing tasks and attending parties.

Bred by Rare Dankness in Colorado, Ghost Train Haze is a cross between Ghost OG and Neville’s Wreck. This multiple Cannabis Cup award winner has sativa-dominant effects, but its buds are dense with a thick blanketing of trichomes—a nod to its indica heritage. (Ghost OG is a variety of the iconic indica hybrid, OG Kush.)

Voted one of the most potent marijuana strains on earth by High Times magazine, Ghost Train Haze is not recommended for beginners or those with a low THC tolerance. Pushing upwards of 23% THC, even the most experienced cannabis consumers should watch their intake of this strain. In low, mediated doses, Ghost Train Haze boosts mood and energy, encouraging laughter and a laid-back but lively demeanor; when taken in the right amounts, Ghost Train Haze can be a great cannabis strain for social gatherings.

In high doses, Ghost Train Haze’s intense cerebral nature becomes evident: psychedelic effects and mental fogginess can make it difficult to focus on work. Go slow with this cannabis strain—overdo it and you may face bouts of paranoia and anxiety, especially if you’re predisposed to these types of behaviors.

This cannabis strain hits quickly and consumers describe a tingle that starts behind the sinus cavities and spreads to the entire body, making it a good fit for medical marijuana users seeking relief from headaches or discomfort caused by glaucoma. Ghost Train Haze’s indica characteristics also provide a full body buzz, so patients looking to ease pain or muscle spasms may also find this strain useful.
