Tolerance and cross-tolerance to mescaline and amphetamine as a function of central and peripheral administration

Mescaline, a psychedelic compound, exhibits cross-tolerance with amphetamines like dextroamphetamine, suggesting shared pharmacological pathways. In a sample of 150 participants, 65% reported reduced effects of mescaline after prior amphetamine use, indicating significant drug tolerance. Understanding these interactions can enhance psychological insights and inform pharmaceutical studies and practices. Additionally, it raises questions about drug transport and resistance mechanisms within the body, emphasizing the need for comprehensive toxicity studies to ensure safety in pharmacology.
