Did Abu Hanifa and early Hanafi’s define intoxication as such?

Said Muhammad [al-Shaybānī]: “Abū Hanīfah informed us, from Sulaymān al-Shaybānī, from Ibn Ziyād, who said that he opened his fast with ‘Abdullāh ibn ‘Umar, and he provided him a drink which seemed to inebriate him. When he awoke in the morn, he enquired, ‘What was this drink? **I was hardly able to find my house!’** **‘Abdullāh replied, ‘We did not give you other than dates and raisins.’ Muhammad said: We adopt this, and it is the position of Abū Hanīfah.”** Kitāb al-Āthār, pp. 699-700 According to al-Tahäwi, **Abü Hanifa and al-Shaybäni claimed that intoxication occurs when an individual cannot differentiate the ground from the sky and a man from a woman,** while Abu Yusuf lowered the bar to a simple slurring of speech. Al-tahawi mukhtasar 1:278 “**From the point of view of Abu Hanifah, intoxication is the state of a person when "intellect has left him so he does not understand a little or much** (anything at all)” - no source i could find Are these statements correct? Was intoxicating described as such. Isn’t it permissible to drink nabidh (from dates) up til the point of intoxication as described And isn’t it permissible to drink non grape/date/raisin drinks till the point described as well? From the perspective of early hanafis.
