Amphetamines are stimulants that impact the central nervous system and are known to cause a range of physiological effects. When ingested, they can lead to increased alertness, energy, and feelings of euphoria. However, one of the significant risks associated with amphetamine use is its impact on the cardiovascular system, which can manifest as hypertension (increased blood pressure) and a higher likelihood of seizures. This is due to their ability to dramatically increase dopamine levels, which can lead to excitability in the brain.

Cocaine also has stimulant properties and can induce seizures and hypertension, but the question specifically asks about the drug that is most typically highlighted in association with these symptoms, particularly in clinical or educational contexts. Marijuana generally does not cause seizures or significantly elevate blood pressure. PCP, while a dissociative drug with its own set of risks, does not primarily cause hypertension and seizures in the same frequency or manner as amphetamines do. Thus, amphetamines serve as the most fitting answer concerning the effects of seizures and hypertension in this context.
