Illicit cigarette is a term used to describe cigarettes that are illegally produced, smuggled, or sold without paying taxes. The term 'REEFER' is a slang term for these cigarettes, which is derived from the word 'REEFER, ' meaning a marijuana cigarette. These cigarettes are often sold at a lower price than those that are legally produced and taxed, making them attractive to buyers who are looking for a cheaper alternative.
