NyQuil has a lot of alcohol. It’s about 10% (20 proof). Robitussin has no alcohol but has DXM which is a hallucinogen. Prescription cough syrup with codeine of course has codeine which is an opioid. Especially with the first two you have to purposely take far above the recommended dosage for it to make you feel high or drunk.
That sounds unbelievable. If your victim is stationary you have to make sure your victim is standing in the right place.
Did she plan to put down Free Bird Seed Here! or something?
Hitting a moving target is even worse. You’d do better to drop the anvil onto the car from a bridge as it passes under.
(Not to give anyone ideas – this, tragically, has been done)
The alcohol is a co-solvent. In short, dextromethorphan (and many other drugs too) dissolves poorly in water, but better in alcohol, so they dissolve it in the alcohol (or sugar alcohols in EtOH-free preparations) and then dissolve it in syrup.
The cherry flavoring is also most often used, because it disguises the unpleasant taste best.
Years ago a woman I knew texted me about her 15 year old daughter. She couldn’t find her. When she searched the house, she found two empty bottles of dextromethorphan cough syrup in daughter’s bedroom.
I explained to her about DXM. I suggested searching the house room by room, looking everywhere. If she still couldn’t find her I suggested calling the police. When she searched the garage, for completeness she popped her car’s trunk, which was where she found daughter dozing.
Because it’s over the counter kids don’t think it’s harmful. You can absolutely overdose on DXM with a slew of dangerous symptoms up to coma and death. Like I mentioned above what can be even more dangerous is if they use the multi-symptom version of robitussen with acetaminophen. If you don’t realize DXM can be dangerous you are probably not thinking about what Tylenol does to your liver at high doses.
Back in the mid 70’s I was prescribed Benylin by my doctor for a bad cough. I was about 6 years old and I can still remember lying in my bed hallucinating like crazy even on the prescribed dose.
That line in ‘Comfortably Numb’: “when I was a child I had a fever, my hands felt just like 2 balloons” always reminds me of my Benylin trip. Although it was my whole body that was a balloon and it was being overinflated and I was scared it would go pop.
I think it contained codeine back in those days, although that has long since been removed in the UK market. They also don’t recommend it for anyone under 10 years old.
Heee !!! This is the best- and references very directly several scenes in Ridley Scott’s 1982 sci-fi epic “Blade Runner”.
Now, for the first time in a couple of decades, I happen to own a state of the art cellular phone. The Galaxy Ultra 24-Pro. It’s lovely. The camera can shoot stills with a 200 Megapixel resolution. Even with THAT, taking a clear photo on a well-lit but overcast day ( the best photographic conditions because the contrast ratio is greatly reduced ), using the good ole " Zoom in and enhance " only goes so far.
When I saw that in the movies, and I’m old, so I did, it was a fun little bit that just flew by. Take a freaking Polaroid-like print and pop it into the viewer and voila !!
By comparison to today’s video technology: Many live sporting events are shot using 8K resolution High Definition cameras. The sheer amount of data per frame is so enormous- and so much MORE than is needed to push out the end result show to users at home most of whom are, at best, viewing on a 4K t.v. monitor- that back at the stadium, in the truck, the Control Room can zoom in rapidly and isolate one part of the frame with startling clarity. I say startling unless you’re the player committing the offense, in which case, of course, you’re mighty pissed that technology has shown you up for the world to see. 
Just in case anyone is unfamiliar with this classic “Red Dwarf” scene.
Person gets in a car, closes door. Someone’s hiding in the back seat and shoots/strangles him or her. I can’t imagine that happening. Even at night, your cabin light comes on and while getting in the car you’re going to notice someone lurking in the back seat.
I’m not so sure. I don’t normally look into the back seat of my car before getting in, because it would never occur to me to wonder whether someone was hiding back there (and so far, no one ever has been).
Ahh, but every time I’ve seen a scene like this, the light doesn’t come on. In my car, it’s actually three lights (and it’s an older car, nowadays there might be more!).
So I think the driver’s an idiot for not noticing that their car’s pitch black inside. Hey, Victim Number Three, you know your ex is strangling anyone who knows his real name, aren’t you the least bit suspicious…?
Someone did actually wake me up by throwing gravel at my window once.
He was coming to bring me and my stuff back from college, didn’t know when he would arrive and it got to being so late I couldn’t keep my eyes open. So I laid down on the (stripped) bed to close my eyes for a moment. Several hours later I woke up as something made a noise on the window.
How do you know? 
The Enterprise (or any other vessel) is in dire trouble, no one knows what to do. But wait! Someone comes up with some bizarre plan that … might … just … work. Spoiler: it ALWAYS works.
But only if someone’s willing to take the unprecedented step of Reversing The Polarity!
Whenever a guest is offered a drink, the host always has a bucket of ice ready on the counter, even if he just got home after being out all day.
Well, there’s not going to be any CCTV left from the starships where it didn’t work, now is there?
Well, if it didnt work and the Enterprise and crew went boom, then we wouldnt know it didnt work- yes? So, we only get the version where it worked.
The sudden and permanent end to the show might be a clue …
They can always use the “speed-of-light breakaway factor” and go back in time to make sure the problem never happens!
You obviously haven’t seen Double Indemnity.
