Diet pills containing caffeine have that effect on some people, as the pill wears off.
Many different compounds are used in ecstasy pills, but the binder is just a small fraction of the pill, its whats used to hold the pill together. Usually Ecstasy pills weigh around 300 mg. A strong pill will contain 90 mg of MDMA. Usually an inert or harmless compound will be used as the filler. Lactose is a common choice for the amateur, but calcium phosphate, sucrose, corn starch, or cellulose could also be used, among other things. Sometimes a mixture of filler and MDMA is just pressed into a pill (gives a crumbly pill), other times a compound like povidone is added to hold the pill together. Many manufactures add other compounds to the pill, for instance caffeine.
No. Aspirin is composed of acetylsalicylic acid and inert filler (such as starch). Benzodiazepine is a completely different compound.
Caffeine pills are made by extracting caffeine from natural sources like coffee beans or tea leaves. The process involves grinding the source material, extracting caffeine using solvents like water or ethyl acetate, filtering the solution, and then drying the extracted caffeine to form a powder. This powder is then compressed into pill form with other ingredients like binders and fillers.
Caffeine increases your blood pressure and heart rate. It stimulates the cardiovascular system. If too much caffeine is present, it can stimulate the heart to the point of ventricular fibrillation, which can lead to rapid cardiac arrest and death. It is very difficult to overdose on caffeine using coffee, but caffeine pills are easy to overdose on and deaths have been reported from caffeine pills. They should be used with caution. One or two of the average caffeine pill should be enough for most people to get a coffee-like buzz.
