Caffeine would be far worse for you if inhaled versus oral ingestion due to how quickly it affects your body. The same is true for cocaine or amphetamines, all of these drugs falling under the category of CNS stimulant. Oral cocaine would be far safer than the ways it is commonly used. Similarly, oral nicotine would be much safer.
