Low-quality cannabis buds
Also called: Shwag, shake, bottom shelf, popcorn, dirt weed, brick weed, ditch weed, Bobby Brown, and more.
Low-quality cannabis is often transported as compact bricks, resulting in a mix of shake, stems, and compressed buds. Typically only found on the black market, shwag tends to be less colorful than your average cannabis, often more brown than green (thus the nickname Bobby Brown -- no relation to the former member of New Edition). It is dry and earthy in aroma with a taste that can be harsh and spicy, as opposed to the sweet and floral notes of top-grade cannabis.
When it's not compacted into brick weed, low-quality buds tend to be light, leafy, and wispy. The concentration of cannabinoids is likely to be very low due to extreme environmental factors, like excessive heat or other variables, which cause trichomes and other crucial parts of the plant to under-develop. The harsh growing conditions typical for low-quality, improperly cared-for cannabis has a tendency to be high in cannabinol (CBN), a byproduct of degradation. Advanced levels of CBN are often attributed to poor or improper storage and handling during transportation.
