Yes — and that's the most economical description of what marijuana does perceptually that I've encountered, because it identifies the precise mechanism rather than just the effect. It doesn't add beauty to things. It removes what was covering the beauty that was already there. The things themselves don't change — the music, the texture of a surface, a face, a light falling across a room — but the habitual film that made them invisible as individual presences, catalogued and therefore no longer seen, gets temporarily dissolved. And in that dissolution they become new — not different, but new, restored to the condition of being encountered for the first time, which is the condition in which their full reality is available.
This connects Proust to your point about marijuana with more precision than the usual "Proust wrote in an altered state" observation allows. Because what Proust was doing structurally — through involuntary memory, through imagination operating on sensation, through the long sentence that suspends and accumulates before closing — was attempting to produce by artistic means what marijuana produces chemically: the removal of the dust of habit from reality, the restoration of things to their full newness, their full presence as themselves rather than as items in a familiar inventory.
The madeleine does exactly this. Combray, by the time Marcel dips the madeleine in the tea, has been buried under decades of habit and voluntary memory's distortions — catalogued, processed, filed away, no longer really seen. The involuntary memory strips all of that accumulated dust away in an instant and restores Combray to the condition of being encountered for the first time, new, full, shining in its complete particularity. The mechanism is different from marijuana's but the phenomenological result is structurally identical — reality made new by the removal of habit's covering.
Which may be why Proust's prose, even read sober, produces something resembling that effect in receptive readers. The long sentence with its suspensions and ramifications and retroactive organizations is itself a device for slowing perception down below the speed of habit, forcing the reader to remain with each detail longer than habitual reading would allow, until the detail begins to yield what it actually contains rather than what the habituated mind assumes it contains. Reading Proust carefully is, in this sense, a practice of de-habituation — the prose itself functioning as a solvent for the dust of repetition, restoring the reader's perception of language, of memory, of time, of other people, to something closer to the newness that marijuana restores to sensory experience.

Which may be why Proust's prose, even read sober, produces something resembling marijuana's effect in receptive readers. The long sentence with its suspensions and ramifications-that seeming to interrupt the text, often seem to be brought about by involuntary memory in its freedom from linearity- and retroactive organizations is itself a device for slowing perception down below the speed of habit, forcing the reader to remain with each detail longer than habitual reading would allow, until the detail begins to yield what it actually contains rather than what the habituated mind assumes it contains.
Reading Proust carefully is, in this sense, a practice of de-habituation, the prose itself functioning as a solvent for the dust of repetition, restoring the reader's perception of language, of memory, of time, of other people, to something closer to the newness that marijuana restores to sensory experience. Both are ways of letting the beauty of things shine through. Both point to the the fact that the beauty was always there, and what obscures it is never the world's poverty but our own desinsitivization to its richness.
Liberated from the ruling of linear, objective time, Proust's prose and the thoughts triggered by marijuana happen in the rythm of the soul, not of temporal chronology. The plant's effect and the Proustian prose, both liberated from the exclusive subjugation to objectivity of linearity, are also a channel for the revelations of involuntary memory and the experience of timelessness. Take the following paragraph by Proust as an example showing many associations of ideas that at first work like digressions, such as when mentioning the church, he adds, "so holy but where we had the right to enter", and then the identification of the anthropomorphic element with the vegetal one, with the inner gesture of the narrator himself, with the mystical dimension, all tied together in an all-encompassing communion between everything, or a shared life between everything. This communion and overarching life is also a characteristic of the reality perceived under marijuana, which increasing not only time but also space, doesn't oblige the fixed limits of categories and separateness, imagination filling in the gaps created by the latter.
"C'est au mois de Marie que je me souviens d'avoir commencé a aimer les aubépines. N'étant pas seulement dans l'église, si sainte, mais ou nous avions le droit d'entrer, posées sur l'autel même, inséparables des mystères `a la celebration desquels elles prenait part, elles faisaient courir aux milieu des flambeaux leur branches attachées horizontalement les unes aux autres en un apprêt de fête, et qu'enjolivaient encore les festons de leur feuillage sur lequel étaient semés a profusion, comme sur une traine de mariée, de petits bouquets de boutons d'une blancheur éclatante. Mais, sans oser les regarder qu'a la dérobée, je sentais que ces apprêts pompeux étaient vivants et que c'était la nature elle même qui, en creusant ces découpures dans les feuilles, en ajoutant l'ornement suprême de ces blancs boutons, avait rendu cette decoration digne de ce qui était a la fois une réjouissance populaire et une solennité mystique. Plus haut, s'ouvrait leurs corolles ça et là avec une grace insouciante, retenant si négligemment comme un dernier et vaporeux atour le bouquet d'étamines, fines comme les fils de la Vierge, qui les embrumait tout entières, qu'en suivant, qu'en essayant the mimer au fond de moi le geste de leur efflorescence, je l'imaginais comme si ç'avait été le mouvement de tête étourdi et rapide, au regard coquet, aux pupilles diminuées, d'une blanche jeune fille, distraite et vive."
("It was in the month of Mary that I remember beginning to love hawthorns. Not only in the church, so holy, but where we had the right to enter, placed on the altar itself, inseparable from the mysteries in whose celebration they participated, they let their branches, tied horizontally to one another in a festive display, run amidst the torches, further embellished by the festoons of their foliage, upon which were sown in profusion, as on a bride's train, small bouquets of dazzling white buds. But, without daring to look at them except furtively, I sensed that these pompous preparations were alive and that it was nature itself which, by carving these shapes in the leaves, by adding the supreme ornament of these white buds, had made this decoration worthy of what was at once a popular rejoicing and a mystical solemnity. Higher up, their corollas here and there with a carefree grace, holding so casually, like a final, vaporous adornment, the bouquet of stamens, fine as the threads of the Virgin, which misted them entirely, that by following, by trying to mimic deep within myself the gesture of their blossoming, I imagined it as if it had been the dizzy and rapid movement of the head, with a coquettish look, with diminished pupils, of a white young girl, distracted and lively.")
The understanding of the Proustian prose and that of reality under the concatenation of ideas that, free from objective time, enchain each other under the effect of marijuana let the beauty of things shine through, and point to the same truth: Beauty was always there, and what obscures it is never the world's poverty but our own enslavement to habit and its objective, pragmatic rythm.
