Can you date a woman with a history of drug abuse?
Conclusion first: Absolutely not.
It's not discrimination, it's probability.I randomly found an article that mentioned: Among 285 surveyed individuals, 282 relapsed within 1 year after detoxification, only 3 did not take drugs again (abstinence time exceeded 1 year), and the relapse rate within 1 year was as high as 98.9%.

I made a 100-sided die simulator, you can play with it yourself. The rule is simple: roll a 100-sided die, only rolling a "1" counts as success.
100-sided die: How low is 1.1%?

Guess how many 1s you can roll in 100 rolls?
Most likely 0. Maybe 1 if you are lucky.
This is the probability of 1%. It sounds like "there is still hope", but in reality it is almost impossible.
And what is the relapse rate for drug addicts? 98.9%.
That is to say, the probability of truly quitting is only 1.1% - even lower than the probability of rolling a 1 with that die.
Many people will say:
"I believe she can change"
"She said it's real this time"
"She has been clean for three months"
"Love can conquer all"
But probability will not change because of your belief.
Imagine 100 drug addicts standing in front of you. Statistically speaking, only 1 person can truly quit. Are you sure you can distinguish who that 1 person is?
Are you sure the person in front of you is that 1%?
Some people might say: What if she is that 1%?
Then I ask you: Are you willing to gamble your life, and your future child's life, on that 1.1%?
If you win the bet, you get a normal partner. If you lose, what you get is:
Money at home being stolen
Being cheated, being used
Domestic violence
Children growing up in this environment
You being dragged down yourself
This is not alarmist talk, this is the real experience of countless families.
Finally, I want to say:
This is not discrimination against drug addicts, they are also victims. But you have no obligation to use your life to save anyone.
Your kindness is precious, please save it for those who deserve it.
