"Synthetic cathinones are frequently found in products sold as ‘research chemicals’, ‘plant food’, ‘bath salts’ or ‘glass cleaner’ and are usually sold in powder, pill or capsule form. Mephedrone (‘m-cat’, ‘meph’, ‘drone’ or ‘miaow’) and methylone (‘explosion’ or ‘top cat’) are usually available as white or brown powders or in the form of pills that are often sold as ‘ecstasy’. Most synthetic derivatives are ingested but may be injected. Mephedrone is commonly nasally insufflated, injected, ingested by swallowing a powder wrapped in paper (‘bombing’), or mixed in a drink."
