Interesting, my only complaint is that the display gets messed up as you scroll down

The black creep up ruins it

I want to see your sources for THC related toxicity. I laughed so hard i dropped my phone when i saw that one. Also seawater in imperial units was written incorrectly, 123lbs instead of what i assume should be oz based on the kg of it. IF i can find a reliable source for your "toxicity" of thc ill be happy to change stars, but until then that alone even being included is laughable.

I thought it my be rather dull, but the author has put together a really interesting mix of compounds. ...... I was disappointed to see multiple poor reviews based entirely in ignorance ("THC can't be toxic; no one dies from it"). If you don't understand why these claims are ridiculous, you probably wouldn't appreciate this app anyway...

Sometimes, I download an app, use it and think it's great. Then I look at the ratings, and think "why are they that bad?" Then I read some reviews, and find out that the users are too stupid for the app. Guys! Gals! The app says that if you eat pure THC nearly tht weight of a bar of chocolate it will kill you in 50% of times. As poisonous substances go, it's rather unpoisonous.

Eh, there are some mistakes, but nothing too severe (sometimes it says g instead of mg). Also, copper-sulfate is next to impossible to kill you when taken per os as it's a powerful emetic and will cause you to expell it all before it gets absorbed in any significant amount. DISCLAIMER: I did say ALMOST! Do NOT try to drink/eat it!

I like the app but I found a error under saltwater. You put 123 lb instead of oz. Its small but I would just like to point out that error.

Struggling to trust half of these as I spotted it said methamphetamine will kill you at 280mg I'm pretty a day for a common userr is 100- 1000mg

It's just a stupid picture with no more information and a bunch of ads.. at least you could link a Wikipedia article to each. Useless

As I went farther down, it loaded less and less on the screen until nothing was visible anymore. Restarted app multiple times. On Note 8.

To all Ignorants saying that THC cannot kill you, first he's talking about pure THC, and second ANY substances are toxic if the dose is important enough, even water can be deadly in excess. PS: great app.

I would like to see where this information. If you are going to put something up for educational purposes please add source information to prove it's validity.

Pau. S. Oct 28, 2017     

Needs an index to look up toxins alphabetically. Scrolling down the scale, I was unable to locate nicotine or nocotinic acid.

I love it, but has 1 lil flaw: there's a typo at glucose, saying it requires 2.something GRAMS of Glucose instead of Kilo Grams. Otherwise, it's awesome and interesting

Nat. P. Apr 4, 2017     

It very interesting to go through and has lots of different things. Wondering if glucose towards the top should be in kg not g.

Mah. Z. Jan 15, 2017     

Very interesting information compared in a lovely way which could be better when provided with sources and links unfortunately though this *app* does exactly what a PDF could've done even better

Jac. D. Nov 23, 2017     

It needs fixed when you scroll down to fast it doesn't load. And there is a small creep up of just black so if you scroll down far enough you can't see anything

Gle. C. Apr 9, 2017     

Great app, love it. FYI the Inland Tiapan is the worlds most venomous land snake, not the Coastal Tiapan.

Eff. S. Oct 15, 2017     

I can't read anything on my phone, text is all blurry. Too bad it looks like an interesting app but unusable here. If i had been able to zoom in or use it with my phone rotated on the side i'd surely give a better score.
