Why do many cigarette smokers become cocaine users?

Are the buzzes similar? How is nicotine related to or similar to cocaine? The cigarette buzz isn't that great IMO. A couple days ago I took 3 really big hits on a Kool regular and I could barely stand up plus I just didn't feel good. I've smoked many a pack of Kool too. Usually I take one big hit after it starts to burn uniformly and I feel a decent buzz after a minute or so. I do not have any desire to do cocaine. All the cocaine users I know are also smokers. Why is that?

There is no addiction connection between cocaine and tobacco.
The only real connection is the addictive personality type of the user.
Nicotine users experience a different high than cocaine users. The buzz is not similar at all.
Be careful doing cocaine. Cocaine in it self is not very dangerous. What is however very dangerous about cocaine use is what dealers will cut it with. Not just the cut either. Some dealers, or coke junkies, will use dirty instruments or have filthy practices that can cause others to contract diseases like hepatitis C and AIDS.
These are not diseases that are curable and will lead to an early death.
Once addicted to cocaine, keeping a steady safe source to buy more is impossible. Normally, any coke dealer, if he or she is smart, doesn't stay in business very long. They know the longer they stay in business the greater the chance is they will get caught.
My personal opionion is that you make friends with others who don't use drugs. Only loosers, and people who don't care about themselves or others do drugs. Much of the money you spend on drugs goes to funding inhumain groups who have no reguard for the safety and lives of the people who work for them. In some cases, drug money buys guns and wepons gangs and other mafisio types use.
Be the real you, stop caring about what others think about you and just be you. Most illegal drugs will take you down a path in life you really don't want to be on. Trust me, I know.
What you seek, you can not find out side of your body. Real happieness and contentment in life comes from with in you. Not by drugs, money, friends, or toys.
Pray hard while you still can. Life is shorter than you think.
