Weird news - Mom drives car, while overdosing on drug

It seems so weird. First of all, those who have not taken drugs and know the danger of drug addition wonder why people get caught up in drug addiction; and then there is the additional case where you wonder how a parent can put their children, especially minor children, at risk through drug addiction. After all, the concept is that minor children do not have all the abilities to survive in this world, and need the support of adults to some degree to survive and thrive; and that parents are hard-wired to care for their children and ensure that they come to no harm.
So this case where a lady was driving a car when she was basically out of control because of having over-dosed on a synthetic drug. It can be so dangerous; can easily have an accident, or drive across a red traffic light and be hit by another vehicle which was driving carefully. And of course, when police come across somebody who is being so dangerous, they are liable to take strict action (link to article):

Police say a Dallas woman was driving with her two children last week when she overdosed on a drug called Brainfreeze. Angela Williams, 37, remains in the Dallas County Jail on a charge of driving while intoxicated with a child under 15, as well as a hot check charge. Her bail is set at $7,000. About 8:20 p.m. last Thursday, Williams parked on a median at Samuell Boulevard and St. Francis Street, apparently having a seizure in her Chevy Malibu, a witness told police. Her two children, ages 11 and 13, told officers that Williams was driving “crazy” and acting irrationally, laughing at nothing in particular. The witness removed both children from the car for their safety, the police report says.
