1 Drugs and Consciousness Psychoactive drugs chemicals that change how you think and feel and usually produces a tolerance using larger and larger doses to experience the same effect. If this happens, quitting will be very difficult because of unpleasant withdrawal effects that indicate a physical dependence and a psychological dependence on the drug. FACTS: Using drugs medically more often doesn’t cause addiction; addiction is not like a disease and can be overcome voluntarily (without therapy) Depressants (drugs that slow and calm neural activity) : Alcohol Impairs judgement and inhibitions and prevents recent events to go into long-term memory. Also, people who are made to believe they are drinking alcohol exhibited less sexual restraints.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
