Final answer:
Over-the-counter (OTC) stimulants typically include pseudoephedrine, which is true as it is commonly found in cold and flu medications. However, its accessibility can vary by region due to regulations to prevent its use in the illegal production of methamphetamine.
Step-by-step explanation:
OTC stimulants often contain the active ingredient pseudoephedrine which is known for its decongestant properties but is also classified as a stimulant. As such, the correct answer to whether OTC stimulants typically include pseudoephedrine is A) True.
Pseudoephedrine is found in many over-the-counter preparations aimed at alleviating symptoms of cold and flu, such as nasal or sinus congestion. Its presence is common in products combined with other substances like antihistamines, guaifenesin, and pain relievers including acetaminophen.
However, due to its potential use as a precursor in the illegal production of methamphetamine, regulations concerning its sale and distribution have tightened. Shoppers may find that they need to provide identification or may be limited in the amount they can purchase at one time. In some regions, pseudoephedrine has been moved behind the pharmacy counter or has been substituted with phenylephrine in over-the-counter products. Therefore, while the ingredient is common, accessibility may vary by region due to these restrictions.
