Drug induced hapiness is not happiness.
Believe me, I'm well aware of that fact.
It's illusory on two levels - one, it's a compromise of your faculties - in other words happiness purchased at a reduced level of function, and two, it's relief from the pain of not having the drug that passes for happiness.
You're correct about the first point, incorrect about the second. If you were correct, then the drug would never be appealing in the first place because the individual would have no discomfort when away from a drug prior to habitual use. Addiction doesn't begin at the moment of first intoxication. For most drugs, addiction comes with habitual use, and the development of predictable habits surrounding the drug use.
Will power is a non-question in face of addiction.
Then no one could quit a drug cold turkey. However, people can accomplish this feat.
That's why AA, NA and so on talk about 'rock bottom' - it's only when the addict reaches rock bottom and weighs the short term misery of quitting against the long-term misery of a lifetime of addiction can they make the choice.
First, AA and NA are pseudo-religious cults. No offense to anyone who has benefited from the programs, they work for some, but I've been there, witnessed and engaged in the ceremony. Be weary of their claims regarding drugs and addiction. I'd recommend less extreme organizations when looking for information.
Second, hitting rock bottom is the moment when you begin to gain enough will power to attempt to climb out of the hole. AA/NA preach that the addict is powerless in the face of the addiction, which is simply false.
To return to the topic of the thread, let me point out that we do not, and cannot, know what being in the box is like without having been in the box. No one has come out, but this does not mean that those inside cannot come out if they like. If nothing else, entering the box with the sincere intention to leave the box at some point in time could provide the rest of humanity with a description of the experience inside the box - maybe even a warning never to enter.
And consider this - if after ten hours, a life support system comes on, perhaps it would be possible to slowly ween the patient off the stimulants and revive him/her. That would at least give me a better chance of getting out of the box alive.
