Psychoactive Substances Classification Chart | Drug Categories & Relationships #305885 (License: Personal Use)

The image displays a hierarchical bubble diagram where substance categories (e.g., benzodiazepines, opiates, hallucinogens) are grouped by color and relative size. Major classes like “mdma,” “lsd,” “cocaine,” “opioids,” and “marijuana” dominate visually, while smaller bubbles represent niche or less common compounds such as “2c-i,” “fentanyl,” or “salvia.” Each bubble’s label denotes a specific drug or chemical, enabling quick comparative analysis of drug families and their relative prominence.

Used on educational, harm-reduction, or clinical pharmacology websites to help users understand drug classification, relative usage, or research focus; ideal for public health resources, academic overviews, or substance use disorder counseling tools.
