Appearance

Poison plants typically present as tall, elegant sativas with narrow, serrated leaves and an open structure. Buds are elongated and often spear-shaped, featuring a high calyx-to-leaf ratio and a shimmering trichome coat. Mature flowers usually display pale to lime-green hues with bright orange pistils, and under optimal lighting, may develop a subtle fox-tailing effect.

Aroma & Flavor

The classic aroma of Poison blends sweet licorice and anise candy with notes of pine needles, damp earth, and subtle herbal spice. Breaking open a cured bud releases a rush of sweet-spice followed by cooling mint and citrus-zest undertones. The flavor profile on the palate starts syrupy-sweet before drying down to pine-resin, anise, and a light peppery finish, often with a faint licorice aftertaste.

Effects

Poison is widely characterized as an energizing, clear-headed sativa that leans toward creativity and focus. It delivers a sparkling cerebral lift rather than a heavy body melt. This strain is known for providing a lively, uplifting experience that is generally considered suitable for daytime consumption.

Terpenes & Cannabinoids

Poison typically tests with moderate to high THC levels and very low CBD. Its terpene profile is often forward with terpinolene, alpha-pinene, and ocimene, contributing to its crisp, green, and sweet tones. Measurable THCV may also appear more often than in many Western hybrids.

Growing

Poison plants exhibit vigorous vertical stretch and medium internodal spacing, supporting aeration and mold resistance. The buds are elongated with a high calyx-to-leaf ratio, producing a fragrant, sticky resin. While pure landrace versions may require longer flowering times, commercial variants may incorporate indica genetics to shorten flowering periods and improve yield.

Origins & Lineage

Durban Poison traces its roots to the port city of Durban in South Africa, where local sativa populations adapted to warm, maritime conditions. During the 1970s and 1980s, seeds were brought to Europe and North America, where it was stabilized for vigor and resin production. Modern commercial variants may include minor indica crosses to optimize for faster finishing times and denser bud structure.
