This is a "straw man". Can you show where someone did that? Put his "faith" in science in the same way that believers put their faith in their religion? I get the feeling, from previous remarks that you have been itching to get this off your chest the entire debate and now you shot your wad prematurely - this the sticky underpants fallacy

Of course you assume smoking weed will have certain effects, you should read something by David Hume.

Structured forms build categorical systems on a floating foundation...
This is an attempt to muddy the waters. Of course all human knowledge is uncertain - thats the human condition - doubt.

ויאמר לא תוכל לראת את פני כי לא יראני האדם וחי

And he (God) said, You cannot see my face - for man shall not see me and live. (2nd book 33)

Moses is asking for certainty - and God is telling him that he cannot have that while he lives.

God goes on to explain that Moses is just going to have to settle for peep of Gods beehind.

Check it out. Its a beautiful moving passage about the doubt that all men must accept.

Just because you have doubt doesnt mean that all bets are equal. Did you ever play poker? Its essentially a game about managing uncertainty - managing it more skillyfully than your opponents. Just because all men men have a weakness does not mean that all men are weak.

Sure you can doubt the very foundations of knowledge, the underpinnings of math and science. And you should! That doesnt mean they are discredited or even that they are the equivalent of all other forms of knowledge.

Ok so you might really be just a brain in a vat. Do you pay your electric bill or not?
