Buried alive in a hotbox
smoke weed in a non ventilated area (a car) with a brick of dry-ice in water lay back and enjoy the trip
Dry-ice replaces oxygen with carbon dioxide making your breaths shorter and shorter this makes any weed smoke like Kush.. 3 people can easily get Ultra-blown hallucinogenic even off 2 bowl of stress.. and it makes kush smoke like killa makes you feel like you smokin weed in space or in a coffin ((Buried alive in a hotbox is very dangerous never attempt without a partner. you could suffocate. long term effects could cause brittle bones and could drain your muscles of calcium))
