"Design a futuristic logo for 'Portal Gas,' a premium cannabis brand. The logo should feature a swirling portal or vortex with gas-like clouds subtly emanating from it. Incorporate sleek, bold typography for 'Portal Gas,' with neon green and deep purple tones on a dark black or space-like background. Add subtle accents of vapor or smoke to represent the 'gas' element, while maintaining a modern and high-end feel. The overall design should have a cosmic, sci-fi touch, evoking the idea of stepping into another dimension of cannabis."
