I can recall having what I thought was a religious experience while under the influence of drugs. Sometimes it seemed as if I was tapping into some kind of secret knowledge about the world and what life was all about.  It seemed as if this information was coming from God.  The Bible tells us that the devil can disguise himself.  This verse helps to explain these experiences:
 
And no marvel; for Satan himself is transformed into an angel of light.
- 2 Corinthians 11:14

In the book "Occult Invasion" author Dave Hunt states on page 177:

"The normal connection between the brain and the human spirit is loosened by drugs, allowing a demonic spirit to operate the brain."

I have lost a sister and my wife has lost a brother, both in an instant... due to drugs and alcohol.  The Bible warns:
 
Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour.
- 1 Peter 5:8

And as it is appointed unto men once to die, but after this the judgment.
- Hebrews 9:27

The bottom line here is this... you too could die in an instant or the Lord Jesus Christ could return at any time now!
 
ARE YOU READY?

The good news is, if you are not ready, you can be.  Will you accept the invitation to receive Jesus Christ as your Lord and Savior right now?
 
For he saith, I have heard thee in a time accepted, and in the day of salvation have I succoured (helped) thee: behold, now is the accepted time; behold, now is the day of salvation.
- 2 Corinthians 6:2
