Create a bold, surreal pop art illustration of a cannabis plant as the central subject. The plant should be large, with dense buds and serrated leaves, rendered in teal and turquoise tones with bright yellow-green highlights and thick black outlines. Set against a gradient sunset background of pink and orange with abstract cloud shapes and splatter textures. Include retro halftone dots and graphic textures to evoke 1980s pop art. Use high-contrast lighting, crisp edges, and a slightly glossy, vector-like finish. The overall mood is vibrant, psychedelic, and contemporary, with no people or text.
