The answer is : three psychoactive drugs.

The coffee, the cigarette and alcohol are all examples of psychoactive drugs.

These drugs or substances act primarily upon the central nervous system where it alters our brain function, changing temporarily our perception, mood, consciousness and behavior.
Even though they are licit, they have the same effect as illicit drugs like: heroin, cannabis, meth, ecstasy and cocaine.

<h2>Further Explanation;</h2>
  • Rocks are classified based on the chemical composition, texture and the way they are formed.  One type of rock may change from one form to another through a rock cycle.
  • Rock cycle is the process through each various rocks change from one form to another, normally an interchange between the three major types of rocks.

There are three major classification of rocks:

<h3>Sedimentary rocks </h3>
