Rescheduling a Schedule I substance, and the Delta-8 controversy by Diana Tran | Blogs, Food / Beverage, Food and BeverageDid you know that in the US, drugs and other chemicals are classified into 5 distinct categories depending on the drug’s acceptable medical use and its potential for abuse or dependency? Drugs federally classified as Schedule I substances by the US Drug Enforcement Administration (DEA) are considered to have the highest potential for abuse and for creating severe psychological and/or physical dependence. In addition to heroin, LSD and MDMA (ecstasy), cannabis is classified as a Schedule I substance in the Controlled Substance Act of 1970, which means it has no approved medical usage.

A rising star in food allergen research: proteomics of shellfish allergen by SCIEX Community | Blogs, Food / Beverage, Life Science Research, ProteomicsIt’s important to know what you’re eating, especially if you suffer from a food allergy. About 220 million people worldwide live with a food allergy.1 These numbers, along with the complexity and severity of conditions, continue to rise. In America, there are about 32 million food allergy sufferers—5.6 million of those are children under the age of 18.2.2 That’s 1 out of every 13 children, or about 2 in every classroom. From a financial perspective, the cost of food allergy childcare for US families is up to $25 billion
