Research chemicals are synthetic substances typically created for scientific and pharmaceutical research purposes. They often mimic the effects of controlled substances, including stimulants, depressants, and hallucinogens, but are not yet well-studied or fully understood in terms of their safety and efficacy. Bath salts are water-soluble minerals designed to enhance the bathing experience. Often infused with essential oils or fragrances, they help relax muscles, soften skin, and promote overall well-being. Common ingredients include Epsom salt, sea salt, and baking soda, which can soothe soreness and improve circulation, making them a popular addition to self-care routines.
